     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to novel substituted imidazoles, and processes for their preparation. The invention also relates to pharmaceutical compositions containing the novel imidazoles and pharmaceutical methods using them, alone and in conjunction with other drugs, especially diuretics and non-steroidal anti-inflammatory drugs (NSAID&#39;s). 
     The compounds of this invention inhibit the action of the hormone angiotensin II (AII) and are useful therefore in alleviating angiotensin induced hypertension. The enzyme renin acts on a blood plasma α 2  -globulin, angiotensinogen, to produce angiotensin I, which is then converted by angiotensin converting-enzyme to AII. The latter substance is a powerful vasopressor agent which has been implicated as a causitive agent for producing high blood pressure in various mammalian species, such as the rat, dog, and man. The compounds of this invention inhibit the action of AII at its receptors on target cells and thus prevent the increase in blood pressure produced by this hormone-receptor interaction. By administering a compound of this invention to a species of mammal with hypertension due to AII, the blood pressure is reduced. The compounds of this invention are also useful for the treatment of congestive heart failure. Administration of a compound of this invention with a diuretic such as furosemide or hydrochlorothiazide, either as a stepwise combined therapy (diuretic first) or as a physical mixture, enhances the antihypertensive effect of the compound. Administration of a compound of this invention with a non-steroidal anti-inflammatory drug (NSAID) can prevent renal failure which sometimes results from administration of a NSAID.

     Furukawa, et al., in U.S. Pat. No. 4,340,598, issued Jul. 20, 1982, discloses hypotensive imidazole derivatives of the formula: ##STR4## wherein R 1  is lower alkyl or, phenyl C 1-2  alkyl optionally substituted with halogen or nitro; R 2  is lower alkyl, cycloalkyl or phenyl optionally substituted; one of R 3  and R 4  is --(CH 2 ) n  COR 5  where R 5  is amino, lower alkoxyl or hydroxyl and n is 0, 1, 2 and the other of R 3  and R 4  is hydrogen or halogen; provided that R 1  is lower alkyl or phenethyl when R 3  is hydrogen, n=1 and R 5  is lower alkoxyl or hydroxyl; and salts thereof. 
     Furukawa et al., in European Patent Application 103,647 discloses 4-chloro-2-phenylimidazole-5-acetic acid derivatives useful for treating edema and hypertension of the formula: ##STR5## where R represents lower alkyl and salts thereof.

     Frazee et al., in European Patent Application 125,033-A discloses 1-phenyl(alkyl)-2-(alkyl)-thioimidazole derivatives which are inhibitors of dopamine-β-hydroxylase and are useful as antihypertensives, diuretics and cardiotonics. 
     European Patent Application 146,228 filed Oct. 16, 1984 by S. S. L. Parhi discloses a process for the preparation of 1-substituted-5-hydroxymethyl-2-mercaptoimidazoles. 
     A number of references disclose 1-benzyl-imidazoles such as U.S. Pat. No. 4,448,781 to Cross and Dickinson (issued May 15, 1984); U.S. Pat. No. 4,226,878 to Ilzuka et al. (issued Oct. 7, 1980); U.S. Pat. No. 3,772,315 to Regel et al. (issued Nov. 13, 1973); U.S. Pat. No. 4,379,927 to Vorbruggen et al. (issued Apr. 12, 1983); amongst others. 
     Pals et al., Circulation Research, 29, 673 (1971) describe the introduction of a sarcosine residue in position 1 and alanine in position 8 of the endogenous vasoconstrictor hormone AII to yield an (octa)peptide that blocks the effects of AII on the blood pressure of pithed rats. This analog, [Sar 1 , Ala 8  ] AII, initially called &#34;P113&#34; and subsequently &#34;Saralasin&#34;, was found to be one of the most potent competitive antagonists of the actions of AII, although, like most of the so-called peptide-AII-antagonists, it also possesses agonistic actions of its own. Saralasin has been demonstrated to lower arterial pressure in mammals and man when the (elevated) pressure is dependent on circulating AII (Pals et al., Circulation Research, 29, 673 (1971); Streeten and Anderson, Handbook of Hypertension, Vol. 5, Clinical Pharmacology of Antihypertensive Drugs, A. E. Doyle (Editor), Elsevier Science Publishers B.V., p. 246 (1984)). However, due to its agonistic character, saralasin generally elicits pressor effects when the pressure is not sustained by AII. Being a peptide, the pharmacological effects to saralasin are relatively shortlasting and are only manifest after parenteral administration, oral doses being ineffective. Although the therapeutic uses of peptide AII-blockers, like saralasin, are severely limited due to their oral ineffectiveness and short duration of action, their major utility is as a pharmaceutical standard. 
     To date there are no known non-peptide antagonists of AII which are useful orally or which bind in vitro in the IC 50  ranges we observe. 
     Some known non-peptide antihypertensive agents act by inhibiting an enzyme, called angiotensin converting enzyme (ACE), which is responsible for conversion of angiotensin I to AII. Such agents are thus referred to as ACE inhibitors, or converting enzyme inhibitors (CEI&#39;s). Captopril and enalapril are commercially available CEI&#39;s. Based on experimental and clinical evidence, about 40% of hypertensive patients are non-responsive to treatment with CEI&#39;s. But when a diuretic such as furosemide or hydrochlorothiazide is given together with a CEI, the blood pressure of the majority of hypertensive patients is effectively normalized. Diuretic treatment converts the non-renin dependent state in regulating blood pressure to a renin-dependent state. Although the imidazoles of this invention act by a different mechanism, i.e., by blocking the AII receptor rather than by inhibiting the angiotensin converting enzyme, both mechanisms involve interference with the renin-angiotensin cascade. A combination of the CEI enalapril maleate and the diuretic hydrochlorothiazide is commercially available under the trademark Vaseretic® from Merck &amp; Co. Publications which relate to the use of diuretics with CEI&#39;s to treat hypertension, in either a diuretic-first, stepwise approach or in physical combination, include Keeton, T. K. and Campbell, W. B., Pharmacol. Rev., 31:81 (1981) and Weinberger, M. H., Medical Clinics N. America, 71:979 (1987). Diuretics have also been administered in combination with saralasin to enhance the antihypertensive effect. 
     Non-steroidal anti-inflammatory drugs (NSAID&#39;s) have been reported to induce renal failure in patients with renal underperfusion and high plasma level of AII. (Dunn, M. J., Hospital Practice, 19:99, 1984). Administration of an AII blocking compound of this invention in combination with an NSAID (either stepwise or in physical combination) can prevent such renal failure. Saralasin has been shown to inhibit the renal vasoconstrictor effect of indomethacin and meclofenamate in dogs (Satoh et al., Circ. Res. 36/37 (Suppl. I):I-89, 1975; Blasingham et al., Am. J. Physiol. 239:F360, 1980). The CEI captopril has been demonstrated to reverse the renal vasoconstrictor effect of indomethacin in dogs with non-hypotensive hemorrhage. (Wong et al., J. Pharmacol. Exp. Ther. 219:104, 1980).

     Pharmaceutically suitable salts include both the metallic (inorganic) salts and organic salts; a list of which is given in Remington&#39;s Pharmaceutical Sciences, 17th Edition, pg. 1418 (1985). It is well known to one skilled in the art that an appropriate salt form is chosen based on physical and chemical stability, flowability, hydroscopicity and solubility. Preferred salts of this invention for the reasons cited above include potassium, sodium, calcium and ammonium salts. 
     Also within the scope of this invention are pharmaceutical compositions comprising a suitable pharmaceutical carrier and a compound of Formula (I), and methods of using the compounds of Formula (I) to treat hypertension and congestive heart failure. The pharmaceutical compositions can optionally contain one or more other therapeutic agents, such as a diuretic or a non-steroidal antiinflammatory drug. Also within the scope of this invention is a method of preventing renal failure resulting from administration of a non-steroidal antiinflammatory drug (NSAID) which comprises administering a compound of Formula (I) in stepwise or physical combination with the NSAID. The compounds of this invention can also be used as diagnostic agents to test the renin angiotensin system. 
     It should be noted in the foregoing structural formula, when a radical can be a substituent in more than one previously defined radical, that first radical can be selected independently in each previously defined radical. For example, R 1 , R 2  and R 3  can each be CONHOR 12 . R 12  need not be the same substituent in each of R 1 , R 2  and R 3  but can be selected independently for each of them.

     SYNTHESIS 
     The novel compounds of Formula (I) may be prepared using the reactions and techniques described in this section. The reactions are performed in a solvent appropriate to the reagents and materials employed and suitable for the transformation being effected. It is understood by those skilled in the art of organic synthesis that the functionality present on the imidazole and other portions of the molecule must be consistent with the chemical transformations proposed. This will frequently necessitate judgment as to the order of synthetic steps, protecting groups required, deprotection conditions, and activation of a benzylic position to enable attachment to nitrogen on the imidazole nucleus. Throughout the following section, not all compounds of Formula (I) falling into a given class may necessarily be prepared by all methods described for that class. Substituents on the starting materials may be incompatible with some of the reaction conditions required in some of the methods described. Such restrictions to the substituents which are compatible with the reaction conditions will be readily apparent to one skilled in the art and alternative methods described must then be used. ##STR39## 
     Generally, compounds of Formula (3) can be prepared by direct alkylation onto imidazole (1) prepared as described in U.S. Pat. No. 4,355,040 and references cited therein, with an appropriately protected benzyl halide, tosylate or mesylate (2) in the presence of base, as shown in path a). Preferably, the metallic imidazolide salt is prepared by reacting imidazole (1) with a proton acceptor such as MH where M is lithium, sodium or potassium in a solvent such as dimethylformamide (DMF) or by reacting it with a metal alkoxide of formula MOR where R is methyl, ethyl, t-butyl or the like in an alcohol solvent such as ethanol or t-butanol, or a dipolar aprotic solvent such as dimethylformamide. The imidazole salt is dissolved in an inert aprotic solvent such as DMF, and treated with an appropriate alkylating agent (2). Alternatively, imidazole (1) can be alkylated with a benzyl halide (2, where X=Br, Cl) in the presence of a base such as sodium carbonate, potassium carbonate, triethylamine or pyridine. The reaction is run in an inert solvent such as DMF or DMSO at 20°  C. to the reflux temperature of the solvent for 1-10 hours. 
     For example, the 4-nitrobenzyl intermediate (3a, wherein R 1  =4-NO 2 , R 2  =R 3  =H) may be obtained by direct alkylation onto imidazole (1) with a 4-nitrobenzyl halide, tosylate or mesylate in the presence of base. 
     If R 7  and R 8  are different, mixtures of two regioisomer alkylation products (3b, and 3c) are obtained in which R 7  and R 8  are interchanged. When R 8  is CHO the alkylation is such that the benzyl group becomes attached to the adjacent nitrogen preferentially. These isomers posses distinct physical and biological properties and can usually be separated and isolated by conventional separation techniques such as chromatography and/or crystallization. ##STR40## 
     In all series examined, the more rapidly eluted isomer of a given pair has greater biological potency than the less rapidly eluted isomer. The absolute structure of the compounds 3d and 3e has been confirmed by X-ray crystallographic analysis to establish the relationship between structure, physical properties and biological activity. Sulfonamide 3d is the more rapidly eluted isomer in its series, acid 3e is the less rapidly eluted isomer in its series. 
     Alternatively, any properly functionalized benzylamine derivative (4) may be converted to imine (6) by treatment with an acylamino ketone (5) in the presence of an inert solvent such as benzene, toluene, or the like, and a catalytic amount of p-toluenesulfonic acid or molecular sieves, N. Engel, and W. Steglich, Liebigs Ann. Chem., 1916, (1978), or in the presence of alumina, F. Texier-Boulet, Synthesis, 679 (1985). The resulting imine (6) can be cyclized to the N-benzyl imidazole (3) with phosphorus pentachloride (PCl 5 ), phosphorus oxychloride (POCl 3 ) or triphenylphosphine (PPh 3 ) in dichloroethane in the presence of a base such as triethylamine, N. Engel and W. Steglich, Liebigs Ann. Chem., 1916, (1978). 
     Acylamino ketone (5) is readily obtainable from amino acids via the Dakin-West reaction, H. D. Dakin, R. West, J. Biol. Chem., 78, 95 and 745 (1928), and various modifications thereof, W. Steglich, G. Hofle, Angew. Chem. Int. Ed. Engl., 8, 981 (1969); G. Hofle, W. Steglich, H. Vorbruggen, Angew. Chem. Int. Ed. Engl., 17, 569 (1978); W. Steglich, G. Hofle, Ber., 102, 883 (1969), or by selective reduction of acyl cyanides, A. Pfaltz, S. Anwar, Tet. Lett. 2977 (1984), or from α-halo, α-tosyl or α-mesyl ketones via the appropriate substitution reactions that one skilled in the art will readily recognize. 
     The functionalized benzylamines (4) may be made from the corresponding benzyl halide, tosylate or mesylate (2) via displacement with a nitrogen nucleophile, a procedure familiar to one skilled in the art. This displacement may be achieved using azide ion, ammonia, or phthalimide anion, etc., in a neutral solvent such as dimethylformamide, dimethylsulfoxide etc., or under phase transfer conditions. The benzyl halide (2) may be made by a variety of benzylic halogenation methods familiar to one skilled in the art, for example benzylic bromination of toluene derivatives with N-bromosuccinimide in an inert solvent such as carbon tetrachloride in the presence of a radical initiator such as benzoyl peroxide at temperatures up to reflux conditions. 
     A wide variety of toluene derivatives may be made from simple electrophilic substitution reactions on an aromatic ring. This includes nitration, sulfonation, phosphorylation, Friedel-Crafts alkylation, Friedel-Crafts acylation, halogenation, and other similar reactions known to one skilled in the art, G. A. Olah, &#34;Friedel-Crafts and Related Reactions,&#34; Vol. 1-5, Interscience, New York, (1965). 
     Another way to synthesize functionalized benzyl halides is via chloromethylation of the corresponding aromatic precursor. Thus, the appropriately substituted benzene ring may be chloromethylated with formaldehyde and hydrochloric acid (HCl) for example with or without an inert solvent such as chloroform, carbon tetrachloride, light petroleum ether or acetic acid. A Lewis acid such as zinc chloride (ZnCl 2 ) or a mineral acid such as phosphoric acid may also be added as a catalyst or condensing agent, R. C. Fuson, C. H. McKeever, Org. Reactions, 1, 63 (1942). 
     Alternatively, N-benzylimidazoles (3) can also be prepared as shown in path b) by forming an R 6  substituted amidine (7) from an appropriately substituted benzylamine (4) which is in turn reacted with an α-haloketone, α-hydroxyketone (8), α-haloaldehyde, or α-hydroxyaldehyde, F. Kunckell, Ber., 34, 637 (1901). 
     As shown in path a), imidazole (1) may be alkylated by a variety of benzyl derivatives. These include compounds with latent acid functionalities such as o, m, and p-cyanobenzylhalides, mesylates or tosylates as shown in path c). Nitriles of formula (9) may be hydrolyzed to carboxylic acids of formula (10) by treatment with strong acid or alkali. Preferably, treatment with a 1:1 (v/v) mixture of concentrated aqueous hydrochloric acid/glacial acetic acid at reflux temperatures for 2-96 hours or by treatment with 1N sodium hydroxide in an alcohol solvent such as ethanol or ethylene glycol for 2-96 hours at temperatures from 20° C. to reflux can be used. If another nitrile group is present it will also be hydrolyzed. The nitrile functionality can also be hydrolyzed in two steps by first stirring in sulfuric acid to form the amide followed by hydrolysis with sodium hydroxide or a mineral acid to give the carboxylic acid (10). 
     The nitriles (9) can be converted into the corresponding tetrazole derivative (11) by a variety of methods using hydrazoic acid. For example, the nitrile can be heated with sodium azide and ammonium chloride in DMF at temperatures between 30° C. and reflux for 1-10 days, J. P. Hurwitz and A. J. Tomson, J. Org. Chem., 26, 3392 (1961). Preferably, the tetrazole is prepared by the 1,3-dipolar cycloaddition of trialkyltin or triaryltin azides to the appropriately substituted nitrile as described in detail by Scheme 15. 
     The starting imidazole compounds (1) are readily available by any of a number of standard methods. For example, acylaminoketone (5) can be cyclized with ammonia or equivalents thereof, D. Davidson, et al., J. Org. Chem., 2, 319 (1937) to the corresponding imidazole as shown in Scheme 1. The corresponding oxazole can also be converted to imidazole (1) by action of ammonia or amines in general, H. Bredereck, et al., Ber., 88, 1351 (1955); J. W. Cornforth and R. H. Cornforth, J. Chem. Soc., 96, (1947). 
     Several alternative routes to imidazoles (1) are illustrated in Scheme 2. As shown in Scheme 2 equation a), reaction of the appropriate R 6  substituted imidate esters (12) with an appropriately substituted α-hydroxy- or α-haloketone or aldehyde (8) in ammonia leads to imidazoles of formula (1), P. Dziuron, and W. Schunack, Archiv. Pharmaz., 307 and 470 (1974). 
     The starting imidazole compounds (1) wherein R 7  and R 8  are both hydrogen can be prepared as shown in equation b) by reaction of the appropriate R 6  -substituted imidate ester (12) with α-aminoacetaldehyde dimethyl acetal (13), M. R. Grimmett, Adv. Heterocyclic Chem., 12, 103 (1970). 
     As shown in equation c), imidazole (15; wherein R 7  =hydrogen and R 8  =CH 2  OH) can be prepared by treatment of the imidate ester (12) with 1,3-dihydroxyacetone (14) in ammonia by the procedure described in Archive der Pharmazie, 307, 470 (1974). Halogenation of imidazole (15) or any imidazole wherein R 7  or R 8  is hydrogen is preferably accomplished by reaction with one to two equivalents of N-halosuccinimide in a polar solvent such as dioxane or 2-methoxyethanol at a temperature of 40°-100° C. for 1-10 hours. Reaction of the halogenated imidazole (16) with a benzylhalide (2) in the manner described in Scheme 1 affords the corresponding N-benzylimidazole (17); wherein R 7  is halogen and R 8  is CH 2  OH). This procedure is described in U.S. Pat. No. 4,355,040. Alternatively, imidazole (17) can be prepared by the procedure described in U.S. Pat. No. 4,207,324. 
     Compounds of formula (17) can also be prepared by treatment of the starting imidazole compound (1) wherein R 7  and R 8  are both hydrogen, with the appropriate benzyl halide followed by functionalization of R 7  and R 8  by treatment with formaldehyde as described in E. F. Godefroi, et al., Recueil, 91, 1383 (1972) followed by halogenation as was described above. 
     As shown in equation d) the imidazoles (1) can also be prepared by reaction of R 6  substituted amidines (18) with an α-hydroxy- or α-haloketone or aldehyde (8) as described by F. Kunckel, Ber., 34, 637, (1901). 
     As shown in equation e), preparation of the nitroimidazoles (1, R 7  or R 8  =NO 2 ) is preferably accomplished by heating the appropriate starting imidazole in a 3:1 mixture of conc. sulfuric acid/conc. nitric acid at 60°-100° C. for 1-6 hours. Nitration of the imidazole (15) can be achieved by first converting the hydroxymethylimidazole to the corresponding chloromethylimidazole (22) employing thionyl chloride or oxalyl chloride. Nitration, as described above, followed by hydrolysis provides the nitroimidazoles (24). 
     Imidazoles (21) where R 7  and R 8  =CN can be prepared as shown in equation f) by reaction of R 6  substituted ortho esters, ortho acids or aldehydes (followed by oxidation of the aldehyde) with diaminomaleonitrile (20) by the procedure described by R. W. Begland et al., J. Org. Chem., 39, 2341 (1974). Likewise, R 6  substituted imidate esters (12) also react with diaminomaleonitrile to give 4,5 dicyanoimidazoles (21). The nitrile groups can be further elaborated into other functional groups by methods familiar to one skilled in the art. 
     Compounds of Formula (1) wherein R 7  =alkyl of 1-6 (straight or branched), phenyl, phenalkyl where alkyl is 1-3 carbon atoms, etc. and R 8  =CH 2  OH can be prepared as shown in equation g). The imidazoles (1) were prepared as described in L. A. Reiter, J. Org. Chem., 52, 2714 (1987). Hydroxymethylation of (1) as described by U. Kempe, et al. in U.S. Pat. No. 4,278,801 provides the hydroxymethylimidazoles (1a). ##STR41## 
     As shown in Scheme 3, path a) for benzylimidazoles (17) where R 7  =Cl and R 8  =CH 2  OH, the hydroxymethyl groups may be easily converted to the corresponding halide, mesylate or tosylate by a variety of methods familiar to one skilled in the art. Preferably, the alcohol (17) is converted to the chloride (25) with thionyl chloride in an inert solvent at temperatures of 20° C. to the reflux temperature of the solvent. 
     Chloride (25) may be displaced by a variety of nucleophiles by nucleophilic displacement reaction procedures familiar to one skilled in the art. For example, excess sodium cyanide in DMSO may be used to form cyanomethyl derivatives (26) at temperatures of 20° C. to 100° C. 
     Nitrile (26) may be hydrolyzed to an acetic acid derivative (27), by a variety of methods. These methods include methods described previously for the hydrolysis of nitriles of formula (9). Examples of desired acids and bases for this hydroylsis include mineral acids such as sulfuric acid, hydrochloric acid, and mixtures of either of the above with 30-50% acetic acid (when solubility is a problem), and alkali metal hydroxides such as sodium hydroxide or potassium hydroxide. The hydrolysis reaction proceeds under heating at temperatures ranging from 50°-160° C. for 2-48 hours. Carboxylic acid (27) may be esterified by a variety of methods without affecting other parts of the molecule. Preferably, (27) is refluxed in a hydrochloric acid/methanol solution for 2-48 hours to give ester (28). 
     Ester (28) may be hydrolyzed to carboxylic acid (27), for instance, after R 1 , R 2  and R 3  have been elaborated. Various methods, acidic or basic, may be used. For example, compound (28) is stirred with 0.5N potassium hydroxide in methanol, or if base soluble, it is stirred in 1.0N sodium hydroxide for 1-48 h at 20° C. to reflux temperatures. 
     Hydroxymethyl derivative (17) may be acylated to give (29) by a variety of procedures. As shown in path b) acylation can be achieved with 1-3 equivalents of an acyl halide or an anhydride in a solvent such as diethyl ether, tetrahydrofuran, methylene chloride or the like in the presence of a base such as pyridine or triethylamine. Alternatively (17) may be acylated by reaction with a carboxylic acid and dicyclohexylcarbodiimide (DCC) in the presence of a catalytic amount of 4-(N,N-dimethylamino)pyridine (DMAP) via the procedure described by A. Hassner, Tet. Lett., 46, 4475 (1978). Treatment of (17) with a solution of carboxylic acid anhydride in pyridine optionally with a catalytic amount of DMAP at temperatures of 20°-100° C. for 2-48 hours is the preferred method. 
     The ether (30) can be prepared from the alcohol (17) as shown in path c) by methods such as treatment of (17) in a solvent such as dimethylformamide or dimethylsulfoxide with potassium t-butoxide, sodium hydride, or the like followed by treatment with R 11  L at 25° C. for 1-20 hours, where L is a halogen, tosylate or mesylate. 
     Alternatively, treatment of (17) with 1-5 equivalents of thionyl chloride in chloroform for 2-6 hours at 25° C. followed by treatment of the intermediate (25) with 1-3 equivalents of MOR 11 , where M is sodium or potassium, for 2-10 hours at 25° C. either in R 11  OH as solvent or in a polar solvent such as dimethylformamide or the like will also yield ether (30). 
     The ether (30) can also be prepared for example by heating (17) for 3-15 hours at 60°-160° C. in R 11  OH containing an inorganic acid such as a hydrochloric acid or sulfuric acid. 
     Compound (17) can be dehalogenated to compound (31) preferably by catalytic hydrogenolysis (over an appropriate catalyst such as 10% palladium on carbon) in methanol at 25° C. for 1-6 hours or by treatment with zinc metal in acetic acid. 
     As shown in Scheme 3, the perfluoroalkylimidazoles (33, R 7  =C v  F 2v+1 ) can be prepared from the corresponding iodoimidazoles (32) by treatment with the appropriate perfluoroalkyl copper reagents [J. Am. Chem. Soc., 108, 832 (1986); J. Fluorine Chem., 27, 291 (1985); J. Fluorine Chem., 22, 541 (1983); Tetrahedron, 25, 5921; (1969); and references cited therein.] Analogously, the pentafluorophenylimidazoles (33; R 7  =C 6  F 5 ) can be produced by the treatment of 32 with pentafluorophenyl copper [Org. Syn., 59, 122 (1980) and references cited therein.] 
     N-arylimidazoles of formula I (compounds wherein r=o) can be prepared by the following methods, it being understood by one skilled in the art that certain manipulations, protecting and deprotecting steps, and other synthetic procedures disclosed above may be necessary to produce compounds with the desired combinations of R 6 , R 7 , R 8  and R 13 . 
     As shown in Scheme 4, equation a) the reaction of aniline derivative (34) with imidate ester (12) to form the substituted amidine (35) provides material which can be cyclized with dihydroxyacetone to form structure (36). Subsequent elaboration into (I) provides the N-arylimidazole compounds of the invention. 
     Alternatively as shown by equation b) the Marckwald procedure, described by Marckwald et. al., Ber., 22, 568, 1353 (1889); Ber., 25, 2354 (1892) can form a 2-mercaptoimidazole (38) from aniline derivative (34) via isothiocyanate (37). Desulfurization of (38) with dilute nitric acid followed by anion formation at the 2-position of the imidazole (39) and reaction with R 6  X where X is Cl, Br, I, allows the formation of (40) which can be subsequently elaborated to I. 
     A variation of Marckwald&#39;s process as shown in equation c) using an α-aminoketone (41) and isothiocyanate (37) can also be employed, see Norris and McKee, J. Amer. Chem. Soc., 77, 1056 (1955) can also be employed. Intermediate (42) can be converted to (I) by known sequences. The general procedure of Carboni et al., J. Amer. Chem. Soc., 89, 2626 (1967) (illustrated by equation d)) can also be used to prepare N-aryl substituted imidazoles from appropriate haloaromatic compounds (43; X=F, Cl, Br) and imidazoles (1): ##STR42## 
     In various synthetic routes R 1 , R 2  and R 3  do not necessarily remain the same from the starting compound to the final products, but are often manipulated through known reactions in the intermediate steps as shown in Schemes 5-22. All of the transformations shown in Schemes 5-10 and 12 and also be carried out on the terminal aromatic ring (i.e., biphenyl ring). ##STR43## 
     As shown in Scheme 5, compounds where R 1  is a sulfonic acid group may be prepared by oxidation of the corresponding thiol (45). Thus, an N-benzylimidazole derivative bearing a thiol group may be converted into a sulfonic acid (46) by the action of hydrogen peroxide, peroxyacids such as metachloroperoxybenzoic acid, potassium permanganate or by a variety of other oxidizing agents, E. E. Reid, Organic Chemistry of Bivalent Sulfur, 1, Chemical Publishing Co., New York, 120-121 (1958). 
     Aromatic hydroxy or thiol groups are obtained from deprotection of the corresponding alkyl ether or thioethers. Thus, for example, a methyl ether or a methyl thioether derivative (44) of an N-benzylimidazole containing one or more aromatic rings may be converted into the free phenol or thiophenol (45) by the action of boron tribromide methyl sulfide, P. G. Willard and C. F. Fryhle, Tet. Lett., 21, 3731 (1980); trimethylsilyl iodide, M. E. Jung and M. A. Lyster, J. Org. Chem., 42, 3761 (1977); KSEt and derivatives thereof, G. I. Feutrill, R. N. Mirrington, Tet. Lett., 1327, (1970), and a variety of other reagents. 
     Alternatively, N-benzylimidazoles may be sulfonated by stirring with H 2  SO 4  at a variety of different concentrations or with other sulfonating agents such as chlorosulfonic acid or sulfur trioxide with or without complexing agents such as dioxane or pyridine at temperatures from 0° to 200° C. with or without solvent, K. LeRoi Nelson in Friedel-Crafts and Related Reactions, III part 2, G. A. Olah, ed., Interscience Publ., 1355 (1964). 
     The synthesis of compounds where R 1  is a sulfate, phosphate or phosphonic acid are depicted in Scheme 6: ##STR44## 
     N-Benzylimidazoles containing a phenolic hydroxyl group (47) may be readily converted into the corresponding sulfate (48) or phosphate (49). As shown in equation a), reaction of the phenol with a sulfur trioxide-amine complex will give the corresponding sulfate (48), E. E. Gilbert, Sulfonation and Related Reactions, Interscience, New York, chapter 6 (1965). Reaction of the phenol (47) with phosphorus pentachloride followed by hydrolysis will give the corresponding phosphate (49), G. M. Kosolapoff, Organophosphorus Compounds, John Wiley, New York, 235 (1950). 
     As shown in equation b) N-benzylimidazoles may be converted into the corresponding phosphonic acids by reaction with phosphorus trichloride (PCl 3 ) and aluminum chloride (AlCl 3 ) in an inert solvent for 0.5-96 hours from temperatures of 25° C. to the reflux temperatures of the solvent. Appropriate workup followed by reaction with chlorine (Cl 2 ) and subsequent hydrolysis of the tetrachloride (51) gives the phosphonic acid derivative (52), G. M. Kosolapoff in Org. Reactions, 6, R. Adams, editor, John Wiley and Sons, New York, 297 (1951). Another more direct route involves reaction of the N-benzylimidazole with PSCl 3  and AlCl 3  followed by hydrolysis, R. S. Edmunson in Comprehensive Organic Chemistry, Vol. 2, D. Barton and W. D. Ollis editors, Pergamon Press, New York, 1285 (1979). 
     Alternatively, equation c) illustrates that aryl phosphonic acids (52) may be formed from reaction of the corresponding diazonium salt (53) with PCl 3  in the presence of Cu(I) followed by hydrolysis with water (ibid, p. 1286). 
     As shown in equation d), the aryl halides (55) may be photolyzed in the presence of phosphite esters to give phosphonate esters (56), R. Kluger, J. L. W. Chan, J. Am. Chem. Soc., 95, 2362, (1973). These same aryl halides also react with phosphite esters in the presence of nickel or palladium salts to give phosphonate esters, P. Tavs, Chem. Ber., 103, 2428 (1970), which can be subsequently converted to phosphonic acids (52) by procedures known to one skilled in the art. 
     N-Benzylimidazoles containing an aldehyde or ketone (57) may be reacted with a phosphorus trihalide followed by water hydrolysis to give α-hydroxyphosphonic acid derivatives, G. M. Kosolapoff, op. cit., 304, as shown in Scheme 7. ##STR45## 
     Compounds where R 1  is --CONHOR 12  may be prepared as shown in Scheme 8, by the treatment of a carboxylic acid (10) with 1-4 equivalents of thionyl chloride for 1-10 hours. This reaction can be run without solvent or in a nonreactive solvent such as benzene or chloroform at temperatures of 25°-65° C. The intermediate acid chloride is then treated with 2-10 equivalents of the appropriate amine derivative, H 2  N--OR 12 , for 2-18 hours at temperatures of 25°-80° C. in a polar aprotic solvent such as tetrahydrofuran or dimethylsulfoxide to give the hydroxamic acid (59). ##STR46## 
     Alternatively, the carboxylic acid (10) can be converted to the hydroxamic acid (59) according to the procedure in J. Med. Chem., 28, 1158 (1985) by employing dicyclohexylcarbodiimide, 1-hydroxybenzotriazole, and H 2  NOR 12  or according to the procedure described in Synthesis, 929 (1985) employing the Vilsmeier reagent and H 2  NOR 12 . 
     Compounds where R 1  is --CONHSO 2  Ar (59a, Ar═phenyl, o-tolyl, etc.) may be produced by treatment of the intermediate acid chlorides from the preparation of the hydroxamic acids (59), with ArSO 2  NHNa. Alternatively, these acylsulfonamides (59a) can be prepared from the carboxylic acids (10) through the corresponding N,N-diphenylcarbamoyl anhydrides (10a) as described by F. J. Brown, et al. in Eur. Pat. Appl. EP 199543 (see Scheme 8). ##STR47## 
     Aniline intermediates (63) are disclosed in U.S. Pat. No. 4,355,040 and may be obtained from the corresponding nitro compound precursor by reduction. A variety of reduction procedures may be used such as iron/acetic acid, D. C. Owsley, J. J. Bloomfield, Synthesis, 118, (1977), stannous chloride, F. D. Bellamy, Tet. Lett., 839, (1984) or careful hydrogenation over a metal catalyst such as palladium. 
     As shown in Scheme 9, aniline intermediates of N-benzylimidazoles may also be prepared from the corresponding carboxylic acid (10) or acid chloride via a Curtius rearrangement of an intermediate acyl azide (60). More modern methods include using diphenylphosphoryl azide as a source of azide, T. Shioiri, K. Ninomiya, S. Yamada, J. Am. Chem. Soc., 94, 6203 (1972), and trapping the intermediate isocyanate (61) produced by the Curtius rearrangement with 2-trimethylsilylethanol and cleaving the resultant carbamate (62) with fluoride to liberate the amine (63), T. L. Capson and C. D. Poulter, Tet. Lett., 25, 3515 (1984). Classical procedures familiar to one skilled in the art may also be employed. 
     Compounds where R 1  is --SO 2  NH 2  may be made as shown in Scheme 10: ##STR48## 
     Sulfonamide compounds (65) may be made by reacting an arylsulfonyl chloride (64) with ammonia, or its equivalent. Unsubstituted arylsulfonamides are made by reaction with ammonia in aqueous solution or in an inert organic solvent, F. H. Bergheim and W. Braker, J. Am. Chem. Soc., 66, 1459 (1944), or with dry powdered ammonium carbonate, E. H. Huntress and J. S. Autenrieth, J. Am. Chem. Soc., 63, 3446 (1941); E. H. Huntress and F. H. Carten, J. Am. Chem. Soc., 62, 511 (1940). 
     The sulfonyl chloride precursor may be prepared by chlorosulfonation with chlorosulfonic acid on the aromatic ring directly, E. H. Huntress and F. H. Carten, ibid.; E. E. Gilbert, op. cit., 84, or by reacting the corresponding aromatic diazonium chloride salt (53) with sulfur dioxide in the presence of a copper catalyst, H. Meerwein, et al., J. Prakt. Chem., [ii], 152, 251 (1939), or by reacting the aromatic sulfonic acid (46) with PCl 5  or POCl 3 , C. M. Suter, The Organic Chemistry of Sulfur, John Wiley, 459 (1948). 
     Linked ester compounds of formula (I) where R 1  is ##STR49## can be made by procedures well known in penicillin and cephalosporin chemistry. The purpose is to provide materials which are more lipophilic and which will be useful orally by rapid transit from the gut into the bloodstream, and which will then cleave at a sufficiently rapid rate to provide therapeutically useful concentrations of the active carboxylic acid form. The following review articles and references cited therein discuss this concept and the chemistry involved in preparing such compounds V. J. Stella, et al., Drugs, 29, 455-473 (1985); H. Ferres, Drugs of Today. 19 (9), 499-538 (1983); A. A. Sirkula, Ann. Repts. Med. Chem., 10, 306-315 (1975). 
     Experimental procedures which are applicable to the preparation of chemically stable linked esters are illustrated by equations a-e of Scheme 11. ##STR50## 
     Compounds of Formula I where R 1  is --C(CF 3 ) 2  OH may be prepared as shown in Scheme 12. ##STR51## 
     Hexafluoroisopropanol compounds (72) may be prepared by treatment of arylsilane (71) with 1-5 equivalents of hexafluoroacetone in a solvent such as methylene chloride at temperatures ranging from about -50° to 25° C. for a period of 2-10 hours. The requisite arylsilane (71) can be prepared using methods known to one skilled in the art such as the procedures described in Chapter 10 of Butterworth&#39;s &#34;Silicon in Organic Chemistry&#34;. ##STR52## 
     As shown in Scheme 13, compound (73) in which X=--NHCO and R 13  =--COOH may be easily prepared, for example, by reacting aniline precursor (63) with a phthalic anhydride derivative in an appropriate solvent such as benzene, chloroform, ethyl acetate, etc. Often the carboxylic acid product will precipitate from solution with the reactants remaining behind, M. L. Sherrill, F. L. Schaeffer, E. P. Shoyer, J. Am. Chem. Soc., 50, 474 (1928). 
     When R 13  =NHSO 2  CH 3 , NHSO 2  CF 3  or tetrazolyl (or a variety of other carboxylic acid equivalents), compound (73) may be obtained by reacting aniline (63) with the requisite acid chloride by either a Schotten-Baumann procedure, or simply stirring in a solvent such as methylene chloride in the presence of a base such as sodium bicarbonate, pyridine, or triethylamine. 
     Likewise, aniline (63) may be coupled with an appropriate carboxylic acid via a variety of amide or peptide bond forming reactions such as DCC coupling, azide coupling, mixed anhydride synthesis, or any other coupling procedure familiar to one skilled in the art. 
     Aniline derivatives (63) will undergo reductive amination with aldehydes and ketones to form secondary amines (74). Thus the aniline is first stirred with the carbonyl compound in the presence of a dehydration catalyst such as molecular sieves or p-toluenesulfonic acid. Afterwards the resultant imine is reduced to the amine with a borohydride reducing agent such as sodium cyanoborohydride or sodium borohydride. Standard catalytic hydrogenation reagents such as hydrogen and palladium/carbon can also be employed. 
     Alternatively, aniline (63) may be monoalkylated by reaction with ethyl formate followed by reduction with, for example, lithium aluminum hydride to produce the N-methyl derivative (74). Anilines (74) may in turn be reacted with carboxylic acid anhydrides and acid chlorides or carboxylic acids by any of the coupling procedures described previously to yield (73) where X=--N(CH 3 )CD--. 
     Aniline (63) or (74) or other intermediate anilines where the amino group may be located on another aromatic ring for example, also react with other anhydrides to make amide-carboxylic acid derivatives of formula (75). Thus, for example, maleic anhydride, 2,3-naphthalenedicarboxylic acid anhydride, and diphenic anhydride are reacted in a similar fashion to phthalic anhydride with aniline (63) or (74) to yield carboxylic acids (76), (77), and (78), respectively. 
     Phthalimide derivatives of aniline (63) may be made by a variety of methods, preferably by stirring aniline (63) with phthalic anhydride in acetic acid at a temperature between 20° C. and reflux, G. Wanag, A. Veinbergs, Ber., 75, 1558 (1942), or by stirring (63) with phthaloyl chloride, a base such as triethylamine, and an inert solvent. 
     Aniline (63) may be converted into its trifluoromethanesulfonamide derivative or its trifluoroacetamido derivative preferably by reacting it with triflic anhydride or trifluoroacetic anhydride and a base such as triethylamine in an inert solvent such as methylene chloride at -78° C. followed by warming to room temperature. 
     Compounds of structure (I) where X is a carbon-carbon linkage which are depicted as (80) can be made as shown in Scheme 14. ##STR53## 
     Equation a) illustrates that the biphenyl compounds (80) can be prepared by alkylation of imidazole (1) with the appropriate halomethylbiphenyl compound (79) by the general procedure described in Scheme 1. 
     The requisite halomethylbiphenyl intermediates (79) are prepared by Ullman Coupling of (81) and (82) as described in &#34;Organic Reactions&#34;, 2, 6 (1944) to provide intermediates (83), which are in turn halogenated. Halogenation can be accomplished by refluxing (83) in an inert solvent such as carbon tetrachloride for 1-6 hours in the presence of a N-halosuccinimide and an initiator such as azobisisobutyronitrile (equation b). 
     As shown in equation c), derivatives of intermediate (83) in which R 13  is at the 2&#39; position (83a) can also be prepared by the method described in J. Org. Chem., 41, 1320 (1976), that is Diels-Alder addition of a 1,3-butadiene to a styrene (84) followed by aromatization of intermediate (85). 
     Alternatively, the substituted biphenyl precursors (83; where R 13  =COOH) and their esters (89) can be prepared as illustrated in equation d), which involves oxazoline compounds as key intermediates, A. I. Meyers and E. D. Mihelich, J. Am. Chem. Soc., 97, 7383 (1975). 
     Further, as shown in Equation e), nickel-catalyzed cross-coupling of an arylzinc halide with a halobenzonitrile yields a biphenylnitrile which can in turn be hydrolyzed by standard methods to afford acid 88. 
     The substituted biphenyl tetrazoles (83; where ##STR54## can be prepared from the nitrile precursors (R 13  =CN) by the methods described in Scheme 1, equation c) and Scheme 15, equation c). 
     However, a preferred method for preparing tetrazoles is described in Scheme 15, equations a) and b). Compounds (90) may be prepared by the 1,3-dipolar cycloaddition of trialkyltin or triphenyltin azides to the appropriately substituted nitrile (83) as in equation a). Alkyl is defined as normal alkyl of 1-6 carbon atoms and cyclohexyl. An example of this technique is described by S. Kozima, et al., J. Organometallic Chemistry, 337 (1971). The required trialkyl or triaryltin azides are made from the requisite commercial trialkyl or triaryl tin chloride and sodium azide. The trialkyl or triaryltin group is removed via acidic or basic hydrolysis and the tetrazole can be protected with the trityl group by reaction with trityl chloride and triethylamine to give (91). Bromination as previously described herein with N-bromosuccinimide and dibenzoylperoxide affords compound (92). Alkylation of (1) with the appropriately substituted benzyl halide using conditions previously described followed by deprotection of the trityl group via hydrolysis affords (80; R 13  =tetrazole). Other protecting groups such as p-nitrobenzyl and 1-ethoxyethyl can be used instead of the trityl group to protect the tetrazole moiety. These groups as well as the trityl group can be introduced and removed by procedures described in Greene, Protective Groups in Organic Synthesis, Wiley-Interscience, (1980). ##STR55## 
     Compounds of structure 93-95 where X is an --O--, --S--, or ##STR56## can be prepared as shown in Scheme 16 by alkylation of imidazole (1) with the appropriate benzyl halide (96). ##STR57## 
     The halomethyldiphenyl ether (109) employed as an alkylating agent in the present invention is prepared as shown in equation b). An Ullman ether condensation of the phenol (97) and a halobenzoic acid as described in Russian Chemical Reviews, 43, 679 (1974) provides the intermediate acid (101). The conversion of (101) into (109) is accomplished by esterification with diazomethane to afford (105) followed by halogenation employing the procedure used in the preparation of (79). The diphenylsulfide (110) and the diphenylamine (111) can be prepared from the appropriate thiophenol (98) or aniline (99) by this procedure. 
     The tertiary diphenylamine (112) can be prepared from the secondary aniline (100) by the above procedure. Alternatively (107) can be alkylated by one of the following procedures: 1) direct alkylation of (107) with R 26  L where L is a leaving group such as a halogen or tosylate employing phase-transfer conditions and ultrasound as described in Tetrahedron Letters, 24, 5907 (1983), 2) treatment of (107) with 1-1.5 equivalents of an appropriate aldehyde and 0.5-5.0 equivalents of sodium cyanoborohydride in a solvent such as methanol at 25° C. at a pH of 3-6 for 1-24 hours, or 3) reductive amination of (107) employing an appropriate carboxylic acid and sodium borohydride as described in J. Am. Chem. Soc., 96, 7812 (1974). The tertiary amine (108) is then halogenated by the procedure previously described to give (112). ##STR58## 
     Compounds of structure (73) where X is --CO-- are prepared as shown in Scheme 17 by alkylation of imidazole (1) with the requisite benzoylbenzyl halides. For example, esters (113) where R 13  is 2--CO 2  CH 3  are prepared by alkylation of imidazole (1) with carbomethoxybenzoyl benzyl halide (114). Ester (113) may be hydrolyzed to the corresponding carboxylic acid (116) by a variety of methods including hydrolysis with a base such as sodium hydroxide or potassium hydroxide in an alcoholic aqueous solvent such as methanol/H 2  O at a temperature from 20° C. to the reflux temperature of the solvent. 
     Carboalkoxybenzoylbenzyl halides (114) are prepared by benzylic halogenation of the corresponding toluoylbenzene precursor by a variety of methods previously described herein. For example, methyl 2-(4-methylbenzoyl)benzoate (115) can be refluxed for 2-48 hours with N-bromosuccinimide, benzoyl peroxide and carbon tetrachloride to effect benzylic bromination. ##STR59## 
     As shown in Scheme 18 the toluoyl ketones (73; where X=CO) may be further transformed into a variety of ketone derivatives including compounds where X is ##STR60## Reaction of ketone (73a) with a hydroxylamine or an appropriately substituted hydrazine will give the requisite oximes (117) and hydrazones (118). Reaction with alcohols in the presence of an acidic catalyst with removal of water will give ketals (119). Reduction, with lithium aluminum hydride, a metal borohydride, zinc/acetic acid or catalytic hydrogenation will give the corresponding alcohol (120) or fully reduced methylene compound (121). These alcohols may be acylated by a variety of anhydrides or acid halides in the presence of a base with or without solvent to give the corresponding esters (122). The alcohols (120) may be converted into their corresponding ethers (123) by reaction of the metal alkoxide with an alkyl halide, mesylate or tosylate in the appropriate solvent or by treatment with a mineral acid in an alcoholic solvent, or by reaction of the alcohol with diazomethane as described in G. Hilgetag and A. Martini, &#34;Preparative Organic Chemistry&#34;, John Wiley, New York, 355-368 (1972). 
     Compounds of formula (I) where X is --OCH 2  --, --SCH 2  --, and --NHCH 2  -- are prepared as shown in Scheme 19. ##STR61## 
     As illustrated in Scheme 19, equation a, hydrolysis of benzyl ether (124) or methyl ether (125) affords hydroxy compound (126) which can be alkylated with the appropriate benzyl halide to give (127). In the case of the methyl ethers (125), the hydrolysis step can be effected by heating the ether at temperatures of 50°-150° C. for 1-10 hours in 20-60% hydrobromic acid, or heating at 50°-90° C. in acetonitrile with 1-5 equivalents of trimethylsilyl iodide for 10-50 hours followed by treatment with water. Hydrolysis can also be carried out by treatment with 1-2 equivalents of boron tribromide in methylene chloride at 10°-30° C. for 1-10 hours followed by treatment with water, or by treatment with an acid such as aluminum chloride and 3-30 equivalents of a sulfur-containing compound such as thiophenol, ethanedithiol, or dimethyl disulfide in methylene chloride at 0°-30° C. for 1-20  hours followed by treatment with water. For compound (124), hydrolysis can be accomplished by refluxing in trifluoroacetic acid for 0.2-1 hours or by catalytic hydrogenolysis in the presence of a suitable catalyst such as 10% palladium on carbon. Deprotonation of (126) with a base, such as sodium methoxide, sodium hydride or the like in a solvent such as dimethylformamide or dimethylsulfoxide at room temperature followed by alkylation with an appropriate benzyl halide at 25° C. for 2-20 hours affords ethers of formula (127), as shown in equation a. 
     The sulfide (129) can be prepared from the thiophenol (45) by the procedure described above to prepare the ether (127) from the phenol (126). The thiophenol (45) can be prepared for example by treatment of the benzylsulfide (128) with sodium in liquid ammonia. 
     The amine (130) can be prepared as shown in equation c, from the aniline (63), itself available from reduction of the corresponding p-nitro compound (3a) which has previously been described. The reductive amination can be carried out by the same procedure as described in Scheme 13 for the preparation of compound (74). 
     Compounds of Formula (I) where the X linkage is --CH═CH--, --CH 2  CH 2  --, and ##STR62## are prepared as shown in Scheme 20. ##STR63## 
     The cis or trans stilbene (132) can be obtained by employing a Wittig reaction between the aldehyde (57) and the phosphorane (131). 
     The stilbene (132) can readily be converted to the saturated derivative (133) for example by catalytic hydrogenation employing a heterogeneous catalyst such as palladium/carbon or platinum/carbon or alternatively with a homogeneous catalyst such as tristriphenylphosphine rhodium chloride. The reduction is performed in a solvent such as benzene, tetrahydrofuran or ethanol at 25° C. under 1-3 atmospheres of hydrogen for 1-24 hours. 
     The cyclopropane (134) can be prepared by treating the stilbene (132) with the Simmons-Smith reagent as described in J. Am. Chem. Soc., 81, 4256 (1959), or by treating (132) with methylene diiodide and copper powder as described in J. Am. Chem. Soc., 101, 2139 (1979), or by treatment with the iron-containing methylene-transfer reagent described in J. Am. Chem. Soc., 101, 6473 (1979). 
     The preparation of compounds of formula (I) where X is --CF 2  CH 2  --, --CF═CH--, --CH═CF--, --CF═CF-- and --CF 2  CF 2  -- are depicted in Scheme 21. ##STR64## 
     Vinylene fluorides (137) and (140) can be prepared by reaction of SF 4  or Et 2  NSF 3  (DAST) with the appropriate ketone (135) or (138) in which Ar bears a methyl group convertible to a benzylic halide suitable for attachment to an imidazole nitrogen, and Ar&#39; bears a cyano, nitro, ester, or other suitable group which can be subsequently converted to CO 2  H, NHSO 2  CF 3 , etc. The initially formed difluoroethylene (136) and (139) can be formed in a non-polar solvent such as methylene chloride and subsequently converted to the vinylene fluoride by means of alumina, or converted directly into the unsaturated fluoride by running the reaction in a polar solvent such as tetrahydrofuran, diglyme or N-methylpyrrolidone in the presence of mineral acid. [Equations a and b]. Experimental details of such procedures are found in D. R. Strobach and G. A. Boswell, J. Org. Chem., 36, 818 (1971); G. A. Boswell, U.S. Pat. Nos. 3,413,321 (1968) and 4,212,515 (1980). 
     As shown in equation c) an appropriate benzoin (141) may be similarly converted to the corresponding 1,2-difluorostilbene (143). Likewise as shown in equation d) an appropriate benzil (144) can be converted to a tetrafluorodiarylethylene (145) using DAST or SF 4 . Experimental details are described in M. E. Christy, et al., J. Med. Chem., 20, (3), 421-430, (1977). 
     Compounds of formula 1 where X= ##STR65## --CH 2  O--, --CH 2  S--, --CH 2  NH--, can be made as shown in Scheme 22. ##STR66## 
     As previously described, acid (10) can be made by alkylating the appropriate imidazole with methyl 4-chloromethylbenzoate in the presence of a base such as potassium carbonate in a polar solvent such as dimethylformamide followed by hydrolysis of the resulting ester. Compound (10) can be converted to (148) by reaction with the requisite amine (146) (R 13  may need to be protected and subsequently deprotected) and dicyclohexyl carbodiimide (DCC) in methylene chloride [J. R. Beek, et al., J. Am. Chem. Soc, 90, 4706 (1968)] or by reaction with tosyl chloride in pyridine [J. H. Brewster and C. J. Ciotti, Jr., J. Am. Chem. Soc., 77, 6214 (1955)]. Yet another process involves conversion of carboxylic acid (10) to its acid chloride with, for example, thionyl chloride followed by reaction with the amine in aqueous base (Schotten-Baumann conditions) or in an organic solvent in the presence of an acid scavenger such as NaHCO 3 , pyridine or triethylamine, or by other procedures known to form an amide bond between an aromatic acid and an amine. 
     The compounds where X=--CH 2  O--, --CH 2  S--, and --CH 2  NH 2  -- can be made as shown in pathway b. The ester (149) is reduced with a reducing agent such as lithium aluminum hydride in an inert solvent to form the alcohol (150) which can then be reacted with tosyl chloride in pyridine to form tosylate (151), which is in turn reacted in the presence of base with a corresponding phenol (152) thiophenol (153), or aniline (146; where R 23  =H) to form compounds (154), (155) or (156). Again this may require that R 13  be protected with a suitable protecting group, however modifications necessary because of specific functional groups are understood to be incorporated by one skilled in the art of organic: synthesis. 
     Alternatively, the alcohol (150) can be converted to the corresponding halide with SOCl 2 , (COCl) 2 , etc, and the resulting halide can then be reacted with a phenol, thiophenol or aniline in the presence of base to form the desired compound, where X is --CH 2  O--, --CH 2  S--, --CH 2  NH-- respectively. ##STR67## 
     Compounds of Formula (I) where X=--SO 2  NR 23  -- and --NR 23  SO 2  -- may be prepared as shown in Scheme 23. As shown in equation a, sulfonylchloride derivative (157) can be reacted with aniline derivative (158) in a solvent in the presence of an acid scavenger such as sodium bicarbonate, triethylamine or pyridine or under Schotten-Baumann like conditions to give (159). Sulfonychloride derivative (157) can be obtained by sulfonation of the corresponding benzyl derivative as described earlier, followed by reaction with PCl 5  or POCl 3 . Likewise, aniline (74) may be reacted in the same manner as described above with sulfonylchloride derivative (160) to give (161). 
     Scheme 24 shows the preparation of furan analogs of the biphenyl compounds (80). Thus, α-ketoester (162), W. Wierenga and H. I. Skulnick, J. Org. Chem., 44, 310 (1979), or the corresponding nitrile (E=CN) can be easily alkylated via standard procedures already mentioned by an alkyl bromide derivative to give (163). The alkene moiety of (163) can be subsequently cleaved by oxidation, for example, with osmium tetroxide, Fieser and Fieser, V.1, p. 812 (Lemieux-Johnson oxidation) to yield dicarbonyl-containing compound (164). Cyclization in mineral acids, acidic ion-exchange resin, POCl 3  /pyridine, or trifluoroacetic anhydride with a catalytic amount of trifluoroacetic acid yields furan (165; Z=O). Reaction of (164) with P 4  S 10 , for example, will yield the corresponding thiophene (165; Z=S). Reaction of (164) with an amine in refluxing benzene, with azeotropic removal of water or by using molecular sieves to absorb the water will yield the corresponding pyrrole (165; Z=NR 11 ). Compounds (166) may be prepared from (165 ) by standard procedures already described. ##STR68## 
     Compounds wherein a methylene group is inserted between the terminal aromatic ring and the acidic functionality may be prepared as shown in Scheme 25, equation a). Thus reduction of ester (167) with, for example, lithium aluminum hydride, gives alcohol (168). Conversion of (168) to the chloride (169) via thionyl chloride followed by reaction with cyanide anion as previously described yields nitrile (170). Compound (170) may be hydrolyzed to carboxylic acid (171) by methods already described or reacted with a hydrazoic acid equivalent to produce tetrazole (172). 
     Compounds wherein R 13  is a trifluoromethylsulfonyl hydrazide acidic functional group were prepared by the procedure described in equation b). That is, conversion of ester (167) to the hydrazide (173) by standard hydrazinolysis followed by reaction with triflic anhydride affords hydrazides (174). ##STR69## 
     The syntheses of compounds wherein R 13  is substituted and unsubstituted 1,2,3-triazoles are described in Scheme 26. Thus reduction of ester (175) with a reducing agent such as lithium aluminum hydride or diisobutylaluminum hydride gives alcohol (176). Oxidation with MnO 2  or pyridinium chlorochromate converts (176) into aldehyde (177). Nitroethylene derivative (178) is prepared by condensation of aldehyde (177) with nitromethane in the presence of a catalyst, R. M. Letcher and M. P. Sammes, J. Chem. Ed., 62, 262 (1985). Reaction of (178) with sodium azide produces the 1,2,3-triazole (179), (N. S. Zefirov, et al., J. Chem. Soc. Chem. Comm., 1001 (1971)) which may be transformed via procedures already described into product (180). 
     Aldehyde (177) can also be converted into substituted 1,2,3-triazoles (183) via the sulfone (181), G. Beck, D. Guunther Chem. Ber., 106, 2758 (1973), followed by reaction with sodium azide to give the 1,2,3-triazole (182). Subsequent standard manipulations lead to 1,2,3-triazoles (183) where E=CN and CO 2  R 11 . The nitrotriazole (183; E=NO 2 ) may be synthesized from the unprotected triazole (179; P=H) via nitration, R. Huttel, et al., Chem. Ber., 88, 1586 (1955), C. L. Habraken and P. Cohen-Fernandes J. Chem. Soc., 37 (1972), or from bromonitroethylene derivative (184), G. Kh. Khisamutdinov, et al., Zh. Org. Khim., 11, 2445 (1975), by reaction with sodium azide. 
     A variety of protecting groups may be used in the manipulation of the above triazoles, amongst which is the trityl group. This group may be easily attached by reaction of the triazole with triphenylmethyl bromide or chloride in an inert solvent such as methylene chloride in the presence of an acid scavenger such as triethyl amine. The trityl group may be later removed by stirring or refluxing in an acidic medium such as trifluoroacetic acid/water, HCl in methylene chloride, or acetic acid/water. The trityl group may also be hydrogenolyzed using a noble metal catalyst such as palladium and hydrogen. ##STR70## 
     The synthesis of trifluoromethyl-1,2,4-triazoles (190) is depicted in Scheme 27. Acid chloride (186) is converted to amide (187) using standard procedures familiar to one skilled in the art. A preferred protecting group is the 2-propionitrile group (P=CH 2  CH 2  CN). Thus (187; P=CH 2  CH 2  CN) can be synthesized from (186) and β-aminopropionitrile under SchottenBaumann like conditions, using aqueous base in an organic solvent to help solubilize (186) and (187). Amide (187) is converted to amidrazone (188) by reaction with PCl 5  or phosgene to make an iminoyl chloride which then in turn is reacted with excess hydrazine. Amidrazone (188) is cyclized to the trifluoromethyl-1,2,4-triazole (189) with trifluoroacetic anhydride and then converted to 190 via bromination, alkylation and deprotection as previously described. ##STR71## 
     Pertinent R 6  groups may be variously introduced by many procedures including those described in Scheme 28 which describes imidazole construction. 
     The R 6  groups so introduced may stand unchanged or may be further elaborated if appropriately functionalized, according to methods familiar to those skilled in the art such as are illustrated in Scheme 28. ##STR72## 
     The 2-alkenylimidazoles (201) can be prepared by bromination of the 2-alkylimidazoles (199) followed by elimination of hydrogen bromide. The bromination is preferably accomplished by UV-irradiation for 1-4 hours of imadazole (199) and N-bromosuccinimide, in an inert solvent, such as carbon tetrachloride at 25° C. Treatment of the intermediate bromide (200) with a base, such as DBU, triethylamine, or potassium t-butoxide, affords the trans 2-alkenylimidazoles (201). Cis alkenyl derivatives (203) are prepared from the trans alkenyl compounds by treatment with osmium tetroxide and sodium periodate to afford aldehydes (202) followed by Wittig reaction. ##STR73## 
     Alternatively, R 6  groups may be introduced by metallation of a protected imidazole or protected 2-methylimidazole followed by addition of an appropriate electrophile as illustrated in Scheme 30, equations a) and b). The products (alcohols, esters, halides, aldehydes, alkyls) are suitable for further elaboration by methods familiar to those skilled in the art. Metallation of imidazoles is described in K. L. Kirk, J. Org. Chem., 43, 4381 (1978); R. J. Sundberg, J. Het. Chem., 14, 517 (1977); J. V. Hay et al., J. Org. Chem., 38, 4379 (1973); B. Iddon, Heterocycles, 23, 417 (1985). 
     Condensation of 2-methylimidazole and appropriate electrophiles (equation b) with catalytic acid or base as described in A. R. Katritzky (Ed.), &#34;Comprehensive Heterocyclic Chemistry&#34;, Vol. 5, p. 431, Pergamon Press, N.Y., 1984 affords products wherein R 6  is alkenyl which are suitable for further elaboration. ##STR74## 
     Various 2-substituted imidazoles can be prepared by reaction of a protected 2-trimethylsilylimidazole with a suitable electrophile by the method described by F. H. Pinkerton and S. F. Thames, J. Het. Chem., 9, 67 (1972), which can be further elaborated as desired. Alternatively, R 6  may also be introduced by nickel catalyzed cross-coupling of Grignard reagents with 2-(methylthio)imidazoles (Scheme 31) as described by E. Wenkert and T. W. Ferreira, J. Chem. Soc., Chem. Commun., 840, (1982); E. Wenkert et al., J. Chem. Soc., Chem. Commun., 637, (1979); and H. Sugimura and H. Takei, Bull. Chem. Soc. Japan, 58, 664 (1985). The 2-(methylthio)imidazoles can be produced by the procedure described in German Patent No. 2,618,370 and the references cited therein. ##STR75## 
     As shown in Schemes 32-35, elaboration of R 8  can be accomplished by procedures described in Schemes 3, 28 and 30b and by chain extension reactions familiar to those skilled in the art in which R 8  bears a reactive terminal functional group, e.g. --OH, halogen, --CHO, --CO 2  R, --CO 2  H, --CH═CH 2 , --NH 2 , --NO 2 , --CN, ##STR76## etc., or by degradation reactions such as conversion of an ester to an acid or an alkene to an aldehyde. 
     Specifically, the hydroxymethyl group can be activated for the displacement reaction by reacting with thionyl chloride, PCl 5  or with carbon tetrachloride/triphenylphosphine to form a corresponding chloro derivative. By a similar reaction bromo and iodo derivatives can be obtained. The hydroxymethyl group can also be activated by forming the corresponding p-toluenesulfonate, methanesulfonate and trifluoromethane sulfonate derivatives. The hydroxyl group can be converted to its corresponding fluoro compound by various fluorinating agents such as DAST as shown in Scheme 32. ##STR77## 
     Also as shown in Scheme 32, the hydroxyl group can be converted to thiolacetic acid derivative (215), J. Y. Gauthier, Tet. Lett., 15 (1986), and to thiol derivative (216) by subsequent hydrolysis. 
     The hydroxymethyl group on compound (17) can be readily oxidized to an aldehyde group by means of manganese dioxide or ceric ammonium nitrate. The aldehyde group will undergo chain extension reactions such as the Wittig and Wittig-Horner reactions and enter into typical carbon-carbon bond forming reactions with Grignard and lithium reagents as well as with compounds bearing activated methylene groups. Alternatively, the hydroxymethyl group can be oxidized directly to an acid functionality which can in turn be converted to ester and amide derivatives. The esters and amides can be prepared directly from the aldehydes by manganese dioxide oxidation in the presence of sodium cyanide and an alcohol or amine, J. Am. Chem. Sec., 90, 5616 (1968) and J. Chem. Soc. (C), 2355 (1971). 
     As shown in Scheme 33, the chlorine on compound (25) can be displaced by the anion of dialkyl malonate to give the corresponding malonate derivative (217). The saponification of (217) with NaOH (or KOH) gives the corresponding diacid which can be decarboxylated to give the corresponding propionic acid derivative (218) by heating to 120° C. Alternatively, (218) can be directly obtained by refluxing (217) with a mineral acid such as HCl or sulfuric acid. The free acid (218) can be esterified by heating in a medium of the various alcohols and a catalytic amount of mineral acids such as HCl or sulfuric acid to give the corresponding esters (219). Alternatively the esters can be obtained by reacting the free acid (218) and the corresponding alcohols in the presence of coupling reagents such as DDQ or EEDQ. A similar reaction with various mono-substituted and disubstituted amines produces the corresponding amides (220). A similar reaction with various mercaptans produces the corresponding thioesters. ##STR78## 
     As shown in Scheme 34, the chloro group on (25) can be displaced by the sodium salt or potassium salt of the alkyl, aryl or arylalkyl mercaptans to give the corresponding sulfide derivatives (221). The amine derivative (222) can be obtained by treating (25) with ammonia or with the corresponding mono-substituted amines. Alternatively, the chloro group may be displaced by sodium azide to give an azide intermediate which upon reduction with H 2  over a noble metal catalyst or with a reducing agent such as chromous chloride (W. K. Warburton, J. Chem. Soc., 2651 (1961)) yields (222) where R 10  and R 11  are hydrogen. This amine c be subsequently alkylated with alkyl halides, or reductively alkylated with aldehydes and ketones to give alkyl derivatives of (222). The amines (222) are converted to the corresponding carbamates (224), sulfonamides (225), amides (226) or ureas (227) by standard procedures illustrated in Scheme 34 and familiar to one skilled in the art. The nitro compound (223) can be obtained by the treatment of (25) with sodium nitrite or potassium nitrite. The nitrate (228) may be synthesized by treatment of (25) with AgNO 3 , A. F. Ferris, et al., J. Am. Chem. Soc., 75, 4078 (1953). ##STR79## 
     The reaction between the thiopyridyl ester (229) and a suitable Grignard reagent produces the ketones (230). ##STR80## 
     As shown in Scheme 36 when the imidazole 4 and/or 5-position contains an aldehyde (231) then derivatives can be formed such as hydrazones (232). Reaction with organometallic reagents such as Grignard or alkyl/aryllithium reagents will yield alcohols (233) which in turn may be transformed into a variety of other functionality familiar to one skilled in the art. ##STR81## 
     Compounds (234) containing an alkyl chain substituted with 4-((2-methoxy)phenyl)piperazine (236) may be prepared by alkylating alkylhalides such as 237 with the piperazine derivative 236 in a solvent such as DMF, ethanol, DMSO, THF, etc., with or without an added acid scavenger such as potassium or sodium carbonate, DBU, etc. as is shown in Scheme 37. An alternative method involves coupling carboxylic acid 238 with piperazine 236 with DCC or any other amide-bond forming reaction familiar to one skilled in the art to yield 239. The amide can then be reduced with lithium aluminum hydride, Red-Al (Lithium tris(trimethoxyethoxy)aluminum hydride), diborane, etc. to yield 234. ##STR82## 
     Alternatively 239 can be prepared via the formation of a nitrogen anion of 236 with a strong base such as n-BuLi, t-BuLi, etc., followed by reaction with ester 240. ##STR83## 
     As shown in Scheme 39, ester 240 may be obtained by esterification of acid 238 (familiar to one skilled in the art) or by direct oxidation of aldehyde 231 with NaCN, MnO 2  in methanol (Corey, E. J., et al. J. Am. Chem. Soc. (1968) 90, 5616). Oxidation of 231 with NaCN, MnO 2 , NH 3  in methanol leads to the corresponding amide 241 (Gilman, N. W. Chem. Comm. (1971) 733). ##STR84## 
     Saponification of ester 240 will lead to carboxylic acid 238. 
     Aldehyde 231, in turn, may be made from the corresponding alcohol 17 by a variety of methods familiar to one skilled in the art, including pyridium chlorochromate (PCC), Swern and ceric ammonium nitrate (CAN) oxidations. 
     Likewise, the unalkylated hydroxymethylimidazole derivative 16 may undergo the transformations to the aldehyde, ester, carboxylic acid and carboxamide by the reactions mentioned above for the alkylated case. 
     The aldehyde functionality on compound 231 may be converted to an acidic heterocycle by the reactions described in Scheme 26. 
     Scheme 41 illustrates that imidazoles, especially those substituted with electron-withdrawing groups react as their anions with 4-nitrofluorobenzene in DMF or DMSO to yield the N-phenylimidazole 245. Compounds such as aldehyde 242, ester 243, and diester 244 work especially well. The nitro group can be further elaborated as in Scheme 13. ##STR85## 
     Scheme 41 illustrates that imidazole 4,5-dicarboxylic acid 246 (prepared by the method of R. G. Fargher and F. L. Pyman (J. Chem. Soc. (1919) 115, 217) can easily be esterified to the diester 247 and then alkylated by the procedures mentioned previously to yield 248. Selective reduction of the diester to the 4-carboalkoxy-5-hydroxymethylimidazole 249 is accomplished with sterically bulky reducing agents such as lithium tri-t-butoxyaluminum hydride. Esters 248 and 249 may be saponified by the usual methods familiar to one skilled in the art. ##STR86##

     To a stirred solution of 25.2 g of methyl 3-iodobenzoate and 21.0 g of 4-iodotoluene at 180°-190° under nitrogen was added 30.3 g of copper powder portionwise over 1 hour. When approximately one-third of the copper had been added, the reaction initiated and the temperature increased spontaneously to 240°. The mixture was allowed to cool to 210°, then was held at 210° during the addition of the remaining copper and for an additional hour. The mixture was allowed to cool to room temperature and was filtered employing benzene as solvent; the resulting filtrate was concentrated in vacuum to provide the crude product. Column chromatography on silica gel (elution=50-100% benzene/hexane) followed by distillation furnished 7.60 g of methyl 4&#39;-methylbiphenyl-3-carboxylate [bp: 114°-115° C. (0.025 torr)] as a colorless oil; NMR (200 MHz, CDCl 3 ): δ 8.27 (br S, 1H); 7.99 (d, 1H);  7.77 (d, 1H); 7.50 (t, 1H); 7.39 (A 2  B 2 , 4H); 3.94 (s, 3H); 2.41 (s, 3H). 
     The following methylbiphenyl starting materials were prepared employing the above procedure.

     Alternatively methyl 4&#39;-methylbiphenyl-2-carboxylate (compound a) and tert-butyl 4&#39;-methylbiphenyl-2-carboxylate can be prepared by chemistry described by A. Meyers via the following five-step procedure. 
     Step 1: Preparation of 2-Methoxybenzoyl chloride 
     To 30 g of 2-anisic acid in 500 mL of round-bottom flask was added dropwise 50 mL of thionyl chloride. After all of the thionyl chloride was added the reaction mixture was stirred at room temperature for 18 hours. Excess thionyl chloride was then distilled off by water aspirator and the remaining liquid was vacuum distilled (82°/0.7 mm Hg). Desired 2-methoxybenzoyl chloride was obtained as a colorless liquid, 32 g. 
     Step 2: Preparation of 4,4-Dimethyl-2-(2-methoxyphenyl)oxazoline 
     20 g of 2-Amino-2-methyl-1-propanol was dissolved in 100 mL of methylene chloride and the mixture was cooled with ice. Meanwhile, 17 g of 2-methoxybenzoyl chloride prepared from Step 1 was placed in a dropping funnel, diluted with 50 mL of methylene chloride and added dropwise. After the addition of the acid chloride, the cooling ice bath was removed and the reaction mixture was stirred at room temperature for 2 hours. 
     The reaction mixture was concentrated to remove the solvent and the solids obtained were triturated with water, collected by filtration and washed with water. Thus obtained solids were dried in vacuo to give a colorless light solid, 20.5 g. 
     The solid was placed in 200 mL of round-bottom flask and 22 mL of thionyl chloride was added slowly to the solid without any solvent. At the beginning of the addition the reaction was vigorous but was controllable. After the addition of thionyl chloride was complete, the yellow reaction mixture was stirred at room temperature for 1 hour. The reaction mixture was poured into 200 mL of ether and the resulting solids were collected and washed with ether. The solids were dissolved in 100 mL of water and the pH of the solution was adjusted to 10 by adding 1N NaOH. The aqueous solution was extracted into ether 3 times. The combined ether extracts were dried (Na 2  SO 4 ) and concentrated to give the desired product as a white solid, 18 g, m.p. 70°-72°. 
     Step 3: Preparation of 2-(4&#39;-Methylbiphenyl-2-yl)-4,4-dimethyloxazoline 
     4-Methylphenyl Grignard reagent was prepared from 2.5 g of magnesium and 13 mL of 4-bromotoluene in 200 mL of anhydrous THF. The Grignard reagent was added to 10 g of the product from Step 2 in 100 mL of anhydrous THF and the reaction mixture was stirred at room temperature for 2 hours. The reaction mixture was concentrated and the residue was treated with 200 mL of saturated NH 4  Cl solution and the mixture was stirred at room temperature for 30 minutes. The aqueous solution was then extracted with ethyl acetate. The crude product obtained upon concentration of the ethyl acetate extracts were purified by flash column chromatography (silica gel, hexane:ethyl acetate=2:1) to give the desired compound as a colorless liquid, 11.8 g. 
     Step 4: Preparation of 4&#39;-Methylbiphenyl-2-carboxylic acid 
     A mixture of 10 g of the product from Step 3 and 200 mL of 4.5N HCl was refluxed for 12 hours. During this period of time the desired compound was isolated as a brownish oil floating on the surface of the reaction medium. The reaction mixture was cooled to room temperature. The product which was oily initially began to solidify upon cooling. The product was extracted with ethyl ether. Upon concentration of the ether extract the desired product was obtained as a colorless solid, 7 g, m.p. 140°-142°. 
     Step 5. Esterification of 4&#39;-methylbiphenyl-2-carboxylic acid 
     Preparation of methyl 4&#39;-methylbiphenyl-2-carboxylate 
     To 100 mL of methanol was added dropwise 5 mL of acetyl chloride with ice cooling. After stirring the mixture for 15 minutes, 5 g of the acid from Step 4 was added at once and the mixture was refluxed for 4 hours. The reaction mixture was concentrated to remove the solvent and the desired methyl ester was obtained as a thick liquid, 5 g. 
     Preparation of tert-butyl 4&#39;-methylbiphenyl-2-carboxylate 
     To a solution of 42.4 g of 4&#39;-methylbiphenyl-2-carboxylic acid in 200 mL of methylene chloride at 0° was added dropwise 20 mL of oxalyl chloride. The reaction was allowed to warm to 25° and then was stirred at 25° for 3 hours. The solvent was removed in vacuo. The residue was dissolved in benzene, and the benzene then removed in vacuo to provide 46.1 g of crude acid chloride. 
     The acid chloride prepared above was dissolved in 600 mL of tetrahydrofuran. To this solution at 0° was added 26.0 g of potassium t-butoxide portionwise such that the reaction temperature did not exceed 15°-20° C. The resulting mixture was then allowed to stir at 25° C. for 1 hour. The reaction mixture was poured into water, and the resulting emulsion was extracted with diethyl ether. The combined organic phases were washed with brine, dried over anhydrous sodium sulfate, filtered, and concentrated. Distillation provided 49.5 g of tertbutyl 4&#39;-methyl-biphenyl-2-carboxylate (bp 115°-120°/0.05 torr). NMR (200 MHz, CDCl 3 ): δ 7.73 (d of d, 1H), 7.46-7.27 (m, 3H); 7.18 (s, 4H); 2.40 (s, 3H); 1.30 (s, 9H). 
     Part B: Preparation of Methyl 4&#39;-bromomethylbiphenyl-3-carboxylate 
     A solution of 7.31 g of Methyl 4&#39;-methylbiphenyl-3-carboxylate, 5.75 g of N-bromosuccinimide, 0.125 g of azo(bisisobutyronitrile), and 500 mL of carbon tetrachloride was refluxed for 3 hours. After cooling to room temperature the resulting suspension was filtered and then concentrated in vacuo to provide 9.90 g of crude methyl 4&#39;-bromomethylbiphenyl-3-carboxylate which was used in a subsequent reaction without further purification; NMR (200 MHz, CDCl 3 ): δ 8.28 (s, 1H); 8.05 (d, 1H); 7.79 (d, 1H); 7.67-7.48 (m, 5H); 4.55 (s, 2H); 3.98 (s, 3H). 
     The following bromomethylbiphenyl intermediates were prepared employing the above procedure.

     EXAMPLE 141 
     Part A: Preparation of 1-[2&#39;-Aminobiphenyl-4-yl)methyl]-2-butyl-4-chloro-5-methoxymethylimidazole 
     A solution of 4.40 g of 1-[(2&#39;-nitrobiphenyl-4-yl)methyl]-2-butyl-4-chloro-5-methoxymethylimidazole, 2.10 g of iron powder, 4.25 mL of glacial acetic acid, and 200 mL of methanol was refluxed for 5 hours. After cooling, the solvent was removed in vacuo, and the residue was dissolved in ethyl acetate. The precipitated iron salts were removed by filtration through Celite®, and the resulting solution was washed with water and brine, dried over anhydrous sodium sulfate and concentrated. Column chromatography on silica gel (elution: 10-30% ethyl acetate/benzene) furnished 2.95 g of 1-[2&#39;-aminobiphenyl-4-yl)methyl]-2-butyl-4-chloro-5-methoxymethylimidazole; NMR (200 MHz, CDCl 3 ): δ 7.43 (d, 2H); 7.19-7.04 (m, 4H); 6.80 (m, 2H); 5.19 (s, 2H); 4.33 (s, 2H); 3.70 (br s, 1H); 3.28 (s, 3H); 2.59 (t, 2H); 1.67 (quint., 2H); 1.34 (sext., 2H); 0.87 (t, 3H). 
     Part B: Preparation of 1-[2&#39;-Trifluoromethanesulfonamidobiphenyl-4-yl)methyl]-2-butyl-4-chloro-5-methoxymethylimidazole 
     To a solution of 2.95 g of 1-[(2&#39;-aminobiphenyl-4-yl)methyl]-2-butyl-4-chloro-5-methoxymethylimidazole and 1.07 mL of triethylamine in 30 mL of methylene chloride at -78° was added 2.59 mL of trifluoromethanesulfonic anhydride dropwise at such rate that the reaction temperature remains below -50°. Following the addition, the reaction mixture was allowed to warm slowly to 25°. At the point the mixture was poured into dilute aqueous acetic acid. The resulting suspension was stirred vigorously for several minutes and then extracted with methylene chloride. The combined organic phases were washed with water and brine, dried over anhydrous sodium sulfate, filtered and concentrated. Column chromatography on silica gel (elution: 20-50% ethyl acetate/benzene) afforded 0.80 g of 1-[(2&#39;-trifluoromethanesulfonamidobiphenyl-4-yl)methyl]-2-butyl-4-chloro-5-methoxymethylimidazole, m.p. 148°-150°; NMR (200 MHz, CDCl 3 ): δ 7.60 (d, 1H); 7.44-7.27 (m, 5H); 7.07 (d, 2H); 5.20 (s, 2H); 4.29 (s, 2H); 3.27 (s, 3H); 2.57 (t, 2H); 1.65 (quint., 2H); 1.35 (sext., 2H); 0.88 (t, 3H).

     5-Aminomethyl-2-butyl-1-[4-(2-carbomethoxybenzoyl)benzyl]-4-chloroimidazole (chromium salt) (500 mg, 1.14 mmol, 1 eq) was dissolved in a mixture of 1.00N NaOH (1.14 mL, 1.14 mmol, 1 eq) and H 2  O (10 mL). Tetrahydrofuran may be added to assist solvation. The solution was cooled to 0° when methyl chloroformate (0.176 mL, 2.28 mmol, 2 eq) in THF (5 mL) was slowly dripped in, in five equal portions, alternating with five portions of 1.00N NaOH (total of 1.14 mL, 1.14 mmol, 1 eq). When the addition was complete, the mixture was stirred at room temperature for 4 hours. Water (100 mL) was added and the pH adjusted to 5 with 1N HCl. The aqueous was extracted with ethyl acetate (3×100 mL), the organic layers dried (MgSO 4 ) and stripped to give a white glass (560 mg).

     Part A: Preparation of 2-Butyl-1-[4-(2-carbomethoxybenzoyl)benzyl]-4-chloro-5-[(trifluoromethylsulfonamido)methyl]imidazole 
     Triflic anhydride (0.21 mL, 1.25 mmol, 1.1 eq) was slowly added to a pyridine (20 mL) solution of the chromium salt of 5-aminomethyl-2-butyl-1-[4-(2-carbomethoxybenzoyl)benzyl]-4-chloroimidazole (0.50 g, 1.1 mmol, 1.0 eq) at 0° C. The solution was allowed to warm to room temperature. After 1.5 hour, 1.5 equivalents of triflic anhydride were added at 0°. After an additional 4 hours at room temperature, water (200 mL) was added and the pH adjusted to 5. The aqueous was extracted with ethyl acetate (3×100 mL) and the organic layers dried (MgSO 4 ) and concentrated to yield 150 mg of a yellow oil which was used as is for the subsequent hydrolysis step.

     Part C: Preparation of 5-t-Butyldimethylsilyloxymethyl-1-[(2&#39;-carbomethoxybiphenyl-4-yl)methyl]-4-chloro-2-(cis-pent-1-en-1-yl)imidazole 
     5-t-Butyldimethylsilyloxymethyl-1-[(2&#39;-carbomethoxybiphenyl-4-yl)methyl]-4-chloroimidazole-2-carboxaldehyde (200 mg) was added all at once to a solution of n-butyltriphenylphosphonium bromide (0.26 g) and potassium t-butoxide (70 mg) in THF at 0° C. The reaction mixture was stirred at room temperature for 15 minutes when it was quenched with saturated aqueous ammonium chloride solution. The mixture was extracted with ethyl acetate, the organic layers washed with water, dried (MgSO 4 ) and the solvent removed in vacuo. The residue was flash chromatographed in hexane/ethyl acetate (5:1) to yield 100 mg of an oil.

     EXAMPLE 315 
     Part A: Preparation of 2-Propyl-4-chloroimidazole-5-carboxaldehyde 
     This example illustrates the preferred procedure for preparing the compound of Example 114. 
     To a solution of 2-propyl-4-chloro-5-hydroxymethylimidazole (prepared according to U.S. Pat. No. 4,355,040; m.p. 110.5°-114° C.; 32.0 g, 0.18 mol) in dichloromethane (1 L) was added activated manganese dioxide (207 g, 2.38 mol, 13 eq.). The mixture was stirred for 4-18 hours at room temperature and subsequently filtered through Celite®. The Celite® was washed with 500 ml of a dichloromethane/methanol solution (1/1, V/V) and the filtrate was concentrated in vacuo to give 24.7 g of a pale yellow solid. Recrystallization from ethyl acetate gave 16.6 g (53%) of pure product; m.p., 139°-141.5° C. 
     NMR (200 MHz; CDCl 3 , CD 3  OD, TMS): δ 9.61 (s, 1H), 2.66 (t, J=7.5 Hz, 2H), 1.83-1.67 (m, 2H), 0.98 (t, J=7 Hz, 3H). 
     Part B: Preparation of 2-Propyl-4-chloro-1[(2&#39;-(1-triphenylmethyltetrazol-5-yl)biphenyl-4-yl-methyl]imidazole-5-carboxaldehyde 
     To a mixture of 2-propyl-4-chloroimidazole-5-carboxaldehyde (15.0 g, 86.9 mmol) and potassium carbonate (13.2 g, 95.6 mmol) in N,N-dimethylformamide (800 ml) was added 4&#39;-bromomethyl-2-(1-triphenylmethyltetrazol-5-yl)biphenyl (prepared according to Example 317, Part B; 53.3 g, 95.6 mmol). The mixture was warmed to 75°-80° C. for 4-18 hours, cooled to room temperature and poured into a separatory funnel containing 1 liter each of water and ethyl acetate. The aqueous phase was extracted twice more with ethyl acetate (250 ml) and the combined organic phase was washed with water (4×500 ml) and saturated aqueous sodium chloride (500 ml), dried over anhydrous magnesium sulfate, filtered and concentrated in vacuo to give the crude product. Flash chromatography on silica gel (1 kg, 10-20% EtOAc/hexanes) gave 27.5 g (49%) of the title compound as a pale yellow solid; m.p. 55°-62° C. 
     NMR (200 MHZ, CDCL 3 , TMS): δ 9.73 (s, 1H), 7.95-6.81 (m, 23H), 5.45 (s, 2H), 2.49 (t, J=7.5 Hz, 2H), 1.75-1.64 (m, 2H), 0.89 (t, J=7 Hz, 3H). 
     Part C: Preparation of 2-Propyl-4-chloro-1-[(2&#39;-(1H-tetrazol-5-yl)biphenyl-4-yl)methyl]imidazole-5-carboxaldehyde 
     To a slurry of 2-propyl-4-chloro-1-[(2&#39;-(1-triphenylmethyletrazol-5-yl)biphenyl-4-yl)methyl]-imidazole-5-carboxaldehyde (26.5 g, 40.8 mmol) in water (100 ml) was added dropwise over 15 minutes 50% aqueous trifluoroacetic acid (V/V, 200 ml). After an additional 15 minutes the mixture was made alkaline with 4N NaOH (350 ml). The resulting mixture was extracted with ether (2×100 ml) and the aqueous phase was acidified to pH 4-5 with 4N HCl and the resulting precipitate was extracted into ethyl acetate (2×100 ml). The combined ethyl acetate layers were dried over anhydrous magnesium sulfate before being filtered and concentrated in vacuo to afford 16 g of the crude product. Flash chromatography on silica gel (100 g, 50% EtOAc/hexanes) provided 13.7 g (83%) of the purified title compound; m.p. 165°-167° C. 
     NMR (200 MHz, CDCl 3 , TMS): δ 9.65 (s, 1H), 7.95-6.96 (m, 8H), 5.51 (s, 2H), 2.59 (t, J=7.5 Hz, 2H), 1.70-1.63 (m, 2H), 0.92 (t, J=7 Hz, 3H).

     2-n-Butyl-4-chloroimidazole-5-carboxaldehyde (10.00 g, 53.6 mmol, 1 eq.) was dissolved in a freshly prepared solution of sodium methoxide (1.23 g Na, 53.6 mmol, 1 eq.) in methanol (175 mL). The methanol was removed in vacuo and replaced with DMF (100 mL). 4-Fluoro-1-nitrobenzene (11.37 mL, 107.0 mmol, 2 eq.) was then added. The mixture was heated at 100° C. for 36 h. Two more equivalents of 4-fluoro-1-nitrobenzene were then added and the mixture heated at 100° C. for an additional 48 hours. The DMF was removed in vacuo and the residue partitioned between ethyl acetate and water. The aqueous phase was extracted twice more with ethyl acetate, the organic layers combined, dried (MgSO 4 ) and the solvent removed in vacuo. Flash chromatography of the residue over silica gel in 9:1 toluene/ethyl acetate yielded 4.92 g (30%) of an amber oil.

     EXAMPLE 354 
     Preparation of 2-n-Butyl-4-chloro-5-[(4-(2-methoxyphenyl)piperazin-1-yl)methyl]-1-[(2&#39;-(1H-tetrazol-5-yl)biphenyl-4-yl)methyl]imidazole 
     The amide in Example 347, Part B (1.01 g, 1.2 mmol, 1 eq.) was dissolved in toluene (25 mL) and to this solution, sodium bis(2-methoxyethoxy)aluminum hydride in toluene (3.4M, 2.44 mL, 8.3 mmol, 7 eq.) was added. The mixture was refluxed for 0.5 h. Water (10 mL) was slowly added (foaming) to quench, followed by the addition of THF (10 mL) and trifluoroacetic acid (5 mL). After 1 hour, the detritylation was complete. The pH was adjusted to 12 with 10N NaOH, and the organic solvents removed in vacuo. More water (30 mL) was added and the trityl alcohol was filtered off as a gum. TLC showed the gum to contain all of the product. The gum was dissolved in methanol, evaporated onto silica gel, and chromatographed in 1:1 hexane/ethyl acetate to 7:3 ethyl acetate/isopropanol, and finally crystallized from hexane/ethyl acetate to yield 189 mg of product as a white solid: m.p. 153.5°-157.5°  C.

     UTILITY 
     The hormone angiotensin II (AII) produces numerous biological responses (e.g. vasoconstriction) through stimulation of its receptors on cell membranes. For the purpose of identifying compounds such as AII antagonists which are capable of interacting with the AII receptor, a ligand-receptor binding assay was utilized for the initial screen. The assay was carried out according to the method described by [Glossmann et al., J. Biol. Chem., 249, 825 (1974)], but with some modifications. The reaction mixture contained rat adrenal cortical microsomes (source of AII receptor) in Tris buffer and 2 nM of  3  H-AII with or without potential AII antagonist. This mixture was incubated for 1 hour at room temperature and the reaction was subsequently terminated by rapid filtration and rinsing through glass micro-fibre filter. Receptor-bound  3  H-AII trapped in filter was quantitated by scintillation counting. The inhibitory concentration (IC 50 ) of potential AII antagonist which gives 50% displacement of the total specifically bound  3  H-AII is presented as a measure of the affinity of such compound for the AII receptor (see Table 20). 
     The potential antihypertensive effects of the compounds of this invention may be demonstrated by administering the compounds to awake rats made hypertensive by ligation of the left renal artery [Cangiano et al., J. Pharmacol. Exp. Ther., 208, 310 (1979)]. This procedure increases blood pressure by increasing renin production with consequent elevation of AII levels. Compounds are administered orally at 100 mg/kg and/or intravenously via a cannula in the jugular vein at 10 mg/kg. Arterial blood pressure is continuously measured directly through a carotid artery cannula and recorded using a pressure transducer and a polygraph. Blood pressure levels after treatment are compared to pretreatment levels to determine the antihypertensive effects of the compounds (See Table 25).

 few compounds (Examples 10, 51, 53A, 59, 77 and 81) did not produce a    
 significant decrease in blood pressure at 10 mg/kg intravenously, but did
 produce some decrease at that level, and it is expected that they would b
 active intravenously at a higher dosage, e.g., 30 mg/kg.

     The hypotensive effects of 2-butyl-4-chloro-1-[2&#39;-(1H-tetrazol-5-yl)biphenyl-4-yl)methyl]-5-hydroxymethylimidazole sodium salt were compared before and after furosemide administration to conscious dogs. Cumulative intravenous injections of imidazole at 0.3 to 3 mg/kg did not lower blood pressure in normotensive conscious dogs (n=4, FIG. 1) but they were effective in inhibiting the pressor response to AII (0.1 μg/kg iv) determined at 10 min post dose (FIG. 2). Plasma renin activity (PRA) in these animals was 1.5±0.5 ng AI/ml/hr. Four days later, furosemide was given to three of these dogs at 10 mg/kg im at 18 and 2 hours before the experiment and increased PRA to 19.9±7.2 ng AI/ml/hr. Imidazole was then given cumulatively iv at the same doses and caused a significant decrease in blood pressure in a dose-dependent manner (FIG. 1). It also inhibited the pressor response to AII at the two higher doses (FIG. 2). A similar hypotensive enhancement by furosemide was also observed with captopril at 0.3  mg/kg iv (FIG. 2). These results indicate that diuretics enhance the hypotensive efficacy of imidazole AII blockers. Thus a combined therapy of these two classes of drugs will be likely to increase the response rate to therapy among hypertensive patients. 
     DOSAGE FORMS 
     The compounds of this invention can be administered for the treatment of hypertension according to the invention by any means that effects contact of the active ingredient compound with the site of action in the body of a warm-blooded animal. For example, administration can be parenteral, i.e., subcutaneous, intravenous, intramuscular, or intra peritoneal. Alternatively, or concurrently, in some cases administration can be by the oral route. 
     The compounds can be administered by any conventional means available for use in conjunction with pharmaceuticals, either as individual therapeutic agents or in a combination of therapeutic agents. They can be administered alone, but are generally administered with a pharmaceutical carrier selected on the basis of the chosen route of administration and standard pharmaceutical practice. 
     For the purpose of this disclosure, a warm-blooded animal is a member of the animal kingdom possessed of a homeostatic mechanism and includes mammals and birds. 
     The dosage administered will be dependent on the age, health and weight of the recipient, the extent of disease, kind of concurrent treatment, if any, frequency of treatment and the nature of the effect desired. Usually, a daily dosage of active ingredient compound will be from about 1-500 milligrams per day. Ordinarily, from 10 to 100 milligrams per day in one or more applications is effective to obtain desired results. These dosages are the effective amounts both for treatment of hypertension and for treatment of congestive heart failure, i.e., for lowering blood pressure and for correcting the hemodynamic burden on the heart to relieve the congestion. 
     The active ingredient can be administered orally in solid dosage forms, such as capsules, tablets, and powders, or in liquid dosage forms, such as elixirs syrups, and suspensions. It can also be administered parenterally, in sterile liquid dosage forms. 
     Gelatin capsules contain the active ingredient and powdered carriers, such as lactose, starch, cellulose derivatives, magnesium stearate, stearic acid, and the like. Similar diluents can be used to make compressed tablets. Both tablets and capsules can be manufactured as sustained release products to provide for continuous release of medication over a period of hours. Compressed tablets can be sugar coated or film coated to mask any unpleasant taste and protect the tablet from the atmosphere, or enteric coated for selective disintegration in the gastrointestinal tract. 
     Liquid dosage forms for oral administration can contain coloring and flavoring to increase patient acceptance. 
     In general, water, a suitable oil, saline, aqueous dextrose (glucose), and related sugar solutions and glycols such as propylene glycol or polyethylene glycols are suitable carriers for parenteral solutions. Solutions for parenteral administration preferably contain a water soluble salt of the active ingredient, suitable stabilizing agents, and if necessary, buffer substances. Antioxidizing agents such as sodium bisulfite, sodium sulfite, or ascorbic acid, either alone or combined, are suitable stabilizing agents. Also used are citric acid and its salts and sodium EDTA. In addition, parenteral solutions can contain preservatives, such as benzalkonium chloride, methyl-or propylparaben, and chlorobutanol. 
     Suitable pharmaceutical carriers are described in Remington&#39;s Pharmaceutical Sciences, A. Osol, a standard reference text in this field. 
     Useful pharmaceutical dosage-forms for administration of the compounds of this invention can be illustrated as follows: 
     CAPSULES 
     A large number of unit capsules are prepared by filling standard two-piece hard gelatin capsules each with 100 milligrams of powdered active ingredient, 150 milligrams of lactose, 50 milligrams of cellulose, and 6 milligrams magnesium stearate. 
     SOFT GELATIN CAPSULES 
     A mixture of active ingredient in a digestible oil such as soybean oil, cottonseed oil or olive oil is prepared and injected by means of a positive displacement pump into gelatin to form soft gelatin capsules containing 100 milligrams of the active ingredient. The capsules are washed and dried. 
     TABLETS 
     A large number of tablets are prepared by conventional procedures so that the dosage unit is 100 milligrams of active ingredient, 0.2 milligrams of colloidal silicon dioxide, 5 milligrams of magnesium stearate, 275 milligrams of microcrystalline cellulose, 11 milligrams of starch and 98.8 milligrams of lactose. Appropriate coatings may be applied to increase palatability or delay absorption. 
     INJECTABLE 
     A parenteral composition suitable for administration by injection is prepared by stirring 1.5% by weight of active ingredient in 10% by volume propylene glycol. The solution is made to volume with water for injection and sterilized. 
     SUSPENSION 
     An aqueous suspension is prepared for oral administration so that each 5 milliliters contain 100 milligrams of finely divided active ingredient, 100 milligrams of sodium carboxymethyl cellulose, 5 milligrams of sodium benzoate, 1.0 grams of sorbitol solution, U.S.P., and 0.025 milliliters of vanillin. 
     The same dosage forms can generally be used when the compounds of this invention are administered stepwise in conjunction with another therapeutic agent. When the drugs are administered in physical combination, the dosage form and administration route should be selected for compatibility with both drugs. Suitable dosages, dosage forms and administration routes are illustrated in Tables 27 and 28.

     When used with an NSAID, the dosage of AII blockers will generally be the same as when the AII blocker is used alone, i.e., 1-500 milligrams per day, ordinarily from 10 to 100 milligrams per day in one or more applications. When used with diuretics, the initial dose of AII blocker can be less, e.g., 1-100 milligrams per day and for the more active compounds 1-10 milligrams per day. 
     It is expected that the compounds of this invention will also be useful in the treatment of chronic renal failure.
