     FIELD OF THE INVENTION 
     The present invention is in the field of medicine, particularly in the treatment of Type II diabetes and obesity. More specifically, the present invention relates to β 3  adrenergic receptor agonists useful in the treatment of Type II diabetes and obesity. 
     BACKGROUND OF THE INVENTION 
     The current preferred treatment for Type II, non-insulin dependent diabetes as well as obesity is diet and exercise, with a view toward weight reduction and improved insulin sensitivity. Patient compliance, however, is usually poor. The problem is compounded by the fact that there are currently no approved medications that adequately treat either Type II diabetes or obesity. 
     One therapeutic opportunity that has recently been recognized involves the relationship between adrenergic receptor stimulation and anti-hyperglycemic effects. Compounds that act as β 3  receptor agonists have been shown to exhibit a marked effect on lipolysis, thermogenesis and serum glucose levels in animal models of Type II (non-insulin dependent) diabetes. 
     The β 3  receptor, which is found in several types of human tissue including human fat tissue, has roughly 50% homology to the β 1  and β 2  receptor subtypes yet is considerably less abundant. Stimulation of the β 1  and β 2  receptors can cause adverse effects such as tachycardia, arrhythmia, or tremors. An agonist that is selective for the β 3  receptor over the β 1  and β 2  receptors is, therefore, more desirable for treating Type II diabetes or obesity relative to a non-selective agonist. 
     However, recent studies have suggested the presence of an atypical beta receptor associated with atrial tachycardia in rats ( Br. J. of Pharmacol.,  118:2085-2098, 1996). In other words, compounds that are not agonists of the β 1  and β 2  receptors can still modulate tachycardia through activation of a yet to be discovered β 4  or through some other unknown pathway. 
     A large number of publications have appeared in recent years reporting success in discovery of agents that stimulate the β 3  receptor. Despite these recent developments, there remains a need to develop a selective β 3  receptor agonist which has minimal agonist activity against the β 1  and β 2  receptors.

     DETAILED DESCRIPTION 
     For the purposes of the present invention, as disclosed and claimed herein, the following terms are defined below. 
     The term “halo” represents fluoro, chloro, bromo, or iodo. 
     The terms “C 1 -C 6  alkyl” and “C 1 -C 4  alkyl” represent a straight, branched or cyclic hydrocarbon moiety having from one to six and one to four carbon atoms, respectively. C 1 -C 4  alkyl groups include methyl, ethyl, n-propyl, isopropyl, cyclopropyl, n-butyl, isobutyl, sec-butyl, t-butyl and cyclobutyl. A “C 1 -C 4  haloalkyl” group is a C 1 -C 4  alkyl moiety substituted with up to six halo atoms, preferably one to three halo atoms. An example of a haloalkyl group is trifluoromethyl. A “C 1 -C 6  alkoxy” group is a C 1 -C 6  alkyl moiety connected through an oxy linkage. 
     The term “divalent hydrocarbon moiety” refers to a straight or branched chain of carbon atoms that may optionally have one or more points of unsaturation. Thus, a hydrocarbon diradical according to the present invention includes alkylene, alkenylene and alkylidene moieties. Examples include but are not intended to be limited to methylene, ethylene, propylene, butylene, —CH(CH 3 )CH 2 ——CH(C 2 H 5 )CH 2 —, —CH(CH 3 )CH(CH 3 )—, —CH 2 C(CH 3 ) 2 —, —CH 2 CH(CH 3 )CH 2 —, —C(CH 3 ) 2 CH 2 —, —CH═CHCH 2 —, —CH═CH—, — C ═CCH 2 —, and the like. 
     The term “optionally substituted” as used herein means an optional substitution of one to three, preferably one or two groups independently selected from oxo, nitro, cyano, phenyl, benzyl, halo, C 1 -C 6  alkyl, C 1 -C 4  haloalkyl, COR 5 , NR 6 R 6 , NR 6 COR 5 , NR 6 SO 2 R 7 , OR 6 , OCOR 5 , OSO 2 R 7 , SR 6 , SOR 7 , SO 2 R 7  or SO 2 NR 6 R 6 ; wherein 
     R 5  is H, C 1 -C 6  alkyl, phenyl, benzyl, C 1 -C 4  haloalkyl, NR 6a R 6a  or OR 6a ; 
     R 6  and R 6a  are independently H, C 1 -C 6  alkyl or phenyl; or when two R 6  or R 6a  groups are attached to the same nitrogen atom, said R 6  or R 6a  groups, together with the nitrogen to which they are attached, may combine to form a piperidine, pyrrolidine, hexamethyleneimine or morpholine ring; and 
     R 7  is C 1 -C 6  alkyl or phenyl. 
     The term “heterocyclic ring” represents a stable, saturated, partially unsaturated, fully unsaturated or aromatic ring, said ring having from one to four heteroatoms that are independently selected from the group consisting of sulfur, oxygen, and nitrogen. The heterocycle may be attached at any point which affords a stable structure. Representative heterocyclic rings include 1,3-dioxolane, 4,5-dihydro-1H-imidazole, 4,5-dihydrooxazole, furan, imidazole, imidazolidine, isothiazole, isoxazole, morpholine, oxadiazole, oxazole, oxazolidinedione, oxazolidone, piperazine, piperidine, pyrazine, pyrazole, pyrazoline, pyridazine, pyridine, pyrimidine, pyrrole, pyrrolidine, tetrazole, thiadiazole, thiazole, thiophene and triazole.

Further specific examples of benzofused and non-benzofused heterocycles are described below in the Preparations and Examples sections. 
     The term “suitable solvent” refers to any solvent, or mixture of solvents, inert to the ongoing reaction that sufficiently solubilizes the reactants to afford a medium within which to effect the desired reaction. 
     The term “patient” includes human and non-human animals such as companion animals (dogs and cats and the like) and livestock animals. Livestock animals are animals raised for food production. Ruminants or “cud-chewing” animals such as cows, bulls, heifers, steers, sheep, buffalo, bison, goats and antelopes are examples of livestock. Other examples of livestock include pigs and avians (poultry) such as chickens, ducks, turkeys and geese. Yet other examples of livestock include fish, shellfish and crustaceans raised in aquaculture. Also included are exotic animals used in food production such as alligators, water buffalo and ratites (e.g., emu, rheas or ostriches). The preferred patient of treatment is a human. 
     The terms “treating” and “treat”, as used herein, include their generally accepted meanings, i.e., preventing, prohibiting, restraining, alleviating, ameliorating, slowing, stopping, or reversing the progression or severity of a pathological condition, or sequela thereof, described herein. 
     The terms “preventing”, “prevention of”, “prophylaxis”, “prophylactic” and “prevent” are used herein interchangeably and refer to reducing the likelihood that the recipient of a compound of formula I will incur or develop any of the pathological conditions, or sequela thereof, described herein. 
     As used herein, the term “effective amount” means an amount of a compound of formula I that is capable of treating conditions, or detrimental effects thereof, described herein or that is capable of agonizing the β 3  receptor. 
     The term “selective β 3  receptor agonist” means a compound that displays preferential agonism of the β 3  receptor over agonism of the β 1  or β 2  receptor. Thus, β 3  selective compounds behave as agonists for the β 3  receptor at lower concentrations than that required for similar agonism at the β 1  and β 2  receptors. A β 3  selective compound also includes compounds that behave as agonists for the β 3  receptor and as antagonists for the β 1  and β 2  receptors. 
     The term “pharmaceutical” when used herein as an adjective means substantially non-deleterious to the recipient patient. 
     The term “formulation”, as in pharmaceutical formulation, is intended to encompass a product comprising the active ingredient(s) (compound of formula I), and the inert ingredient(s) that make up the carrier, as well as any product which results, directly or indirectly, from combination, complexation or aggregation of any two or more of the ingredients, or from dissociation of one or more of the ingredients, or from other types of reactions or interactions of one or more of the ingredients. Accordingly, the pharmaceutical formulations of the present invention encompass any composition made by admixing a compound of the present invention and a pharmaceutical carrier. 
     The term “unit dosage form” refers to physically discrete units suitable as unitary dosages for human subjects and other non-human animals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, in association with a suitable pharmaceutical carrier. 
     Because certain compounds of the invention contain an acidic moiety (e.g., carboxy), the compound of formula I may exist as a pharmaceutical base addition salt thereof. Such salts include those derived from inorganic bases such as ammonium and alkali and alkaline earth metal hydroxides, carbonates, bicarbonates, and the like, as well as salts derived from basic organic amines such as aliphatic and aromatic amines, aliphatic diamines, hydroxy alkamines, and the like. 
     Because certain compounds of the invention contain a basic moiety (e.g., amino), the compound of formula I can also exist as a pharmaceutical acid addition salt. Such salts include the salicylate, sulfate, pyrosulfate, bisulfate, sulfite, bisulfite, phosphate, mono-hydrogenphosphate, dihydrogenphosphate, metaphosphate, pyrophosphate, chloride, bromide, iodide, acetate, propionate, decanoate, caprylate, acrylate, formate, isobutyrate, heptanoate, propiolate, oxalate, malonate, succinate, suberate, sebacate, fumarate, maleate, 2-butyne-1,4 dioate, 3-hexyne-2,5-dioate, benzoate, chlorobenzoate, hydroxybenzoate, methoxybenzoate, phthalate, xylenesulfonate, phenylacetate, phenylpropionate, phenylbutyrate, citrate, lactate, hippurate, β-hydroxybutyrate, glycolate, maleate, tartrate, methanesulfonate, propanesulfonate, naphthalene-1-sulfonate, naphthalene-2-sulfonate, mandelate and like salts. Preferred acid addition salts include the hemi-fumarate, benzoate, salicylate, R-mandelate, hydrochloride and glycolate salts. 
     It is recognized that various stereoisomeric forms of a compound of formula I exist. The compounds may be prepared as racemates and can be conveniently used as such. Therefore, the racemates, individual enantiomers, diastereomers, or mixtures thereof form part of the present invention. Unless otherwise specified, whenever a compound is described or referenced in this specification all the racemates, individual enantiomers, diastereomers, or mixtures thereof are included in said reference or description. 
     It is also recognized that various tautomeric forms of a compound of formula I may exist, and all tautomeric forms are part of the present invention. Unless otherwise specified, whenever a compound is described or referenced in this specification all tautomeric forms, or mixtures thereof, are included in said reference or description.

     Synthesis 
     The compound of formula I may be prepared as described in the following Schemes and Examples.                           
     The reaction of Scheme 1 may be carried out under conditions appreciated in the art for the amination of epoxides. For example, the epoxide of formula II may be combined with an amine of formula III in a lower alcohol, dimethylformamide, dimethylsulfoxide, or acetone, preferably ethanol, isopropanol, n-butanol or t-butanal, at room temperature to the reflux temperature of the reaction mixture, preferably between 40° C.-90° C. The reaction may also be carried out under conditions generally described in Atkins, et al.,  Tet. Let.,  27:2451, 1986. These conditions include mixing the reagents in the presence of trimethylsilyl acetamide in a polar aprotic solvent such as acetonitrile, dimethylformamide, acetone, dimethylsulfoxide, dioxane, diethylene glycol dimethyl ether, tetrahydrofuran, or other polar aprotic solvents in which the reagents are soluble. 
     The compound of formula I may also be prepared via a Suzuki coupling as shown in Scheme 2.                           
     A compound of formula IV may be reacted with a compound of formula III as described above in Scheme 1. The compound of formula V (an aryl halide) may then be reacted with a heteroaryl boronic acid, an aryl boronic ester, or an aryl boronic cyclic ester, preferably an aryl boronic acid, under conditions appreciated in the art for the coupling of aromatic halides with aryl boronic acids and their derivatives. This coupling is known in the art generally as a Suzuki coupling. The skilled artisan will recognize that an aryl triflate may also be employed in the present Suzuki coupling as an alternative to employing an aryl halide. 
     The epoxide starting materials employed in Schemes 1 and 2 may be prepared by techniques recognized and appreciated by one skilled in the art. See, e.g., U.S. Pat. No. 4,663,334; European Patent Application 171209; Korn, et al.,  J. Pharm. Sci.,  69(9):1010-13, 1980 and references cited below in the Preparations section for representative and/or analogous procedures for preparing the epoxides of formula II and IV. To illustrate, epoxides of formula II, where X is OCH 2  or SCH 2 , may be prepared according to the procedure detailed in Scheme 3 wherein R 9  is OH or SH and X′ is OCH 2  or SCH 2 .                           
     Equimolar amounts of a compound of formula VI and (2S)-(+)-glycidyl 3-nitrobenzenesulfonate may be dissolved in an inert solvent such as acetone and treated with a slight excess of a weak base, such as potassium carbonate. The suspension may then be heated at reflux for 16-20 hours with stirring to provide a compound of formula II(a). Compounds of formula IV, where X is OCH 2  or SCH 2 , may be prepared in an analogous fashion. 
     The amino starting materials employed in Schemes 1 and 2 (formula III compound) may also be prepared by techniques recognized and appreciated by one skilled in the art. For example, an amine of formula III, where X 2  is O, may be prepared according to the procedure detailed in Scheme 4.                           
     A compound of formula IX may be prepared by reacting an arylalkyl alcohol of formula VII with excess (5 mol/equivalent) formula VIII compound by methods well known in the art (see, e.g.,  Sh. Prikl. Kin.,  45:1573-77, 1972). The reaction may also be carried out by mixing the reagents in an aprotic solvent, preferably diglyme, and adding potassium t-butoxide (0.5 mol/equivalent). The reaction is typically heated at reflux until water present in the reaction mixture is removed (generally 2-8 hours). A compound of formula X may then be prepared by hydrogenation of the corresponding compound of formula IX over a precious metal catalyst. The hydrogenation can be affected at between 20 and 60 psi of hydrogen (preferably 50 psi), and with a variety of solvents (preferably methanol/acetic acid), temperatures (preferably 50° C.), and catalysts (preferably 5% palladium on carbon wetted with ethanol denatured with toluene) well known in the art. 
     A skilled artisan will appreciate that a compound of formula X could be coupled with a wide variety of halides to yield the claimed ethers. The coupling can be carried out according to procedures well known in the art and is preferably performed by mixing the starting materials in N,N-dimethylacetamide and toluene in the presence of potassium carbonate. The reaction is typically then heated to reflux for 5 to 24 hours to effect the reaction and to remove water present in the reaction mixture. 
     Compounds of formula VI, VII and VIII are either commercially available, known in the art, or can be prepared by methods known in the art or described herein. 
     The following Preparations, Examples and Formulations are provided so that the invention might be more fully understood. They should not be construed as limiting the invention in any way.

     Epoxide 1 
     A mixture of 2-(1-methylpyrazol-5-yl)phenol (4.65 mmol, 810 mg), (2S)-glycidyl 3-nitrobenzenesulfonate (5.58 mmol, 1.45 g), potassium carbonate (5.58 mmol, 771 mg) and acetone (40 ml) are refluxed for 16 hours, cooled to room temperature and the solids removed via filtration. The filtrate is concentrated and the crude product purified on silica gel (40% ethyl acetate/hexane) to give 956 mg of the title epoxide. 
     Epoxide 2 
     Methyl hydrazine (23.2 mmol, 1.23 ml) is added to a solution of 2-(3-hydroxy-2-propen-1-on-1yl)phenol ( J. Am. Chem. Soc.,  72:3396, 1950), 15.4 mmol, 2.54 g) in methanol (7 ml) and the mixture is heated at 100° C. for one hour. After cooling, the reaction mixture is diluted with water (100 ml) and stirred for one hour. The precipitate is collected via filtration and purified on silica gel (30% ethyl acetate/hexane) to give 811 mg of 2-(1-methylpyrazol-3-yl)phenol. 
     A mixture of 2-(1-methylpyrazol-3-yl)phenol (4.59 mmol, 800 mg), (2S)-glycidyl 3-nitrobenzenesulfonate (5.51 mmol, 1.42 g), potassium t-butoxide (5.51 mmol, 515 mg) and tetrahydrofuran (30 ml) are refluxed for 16 hours, cooled to room temperature and poured into saturated aqueous ammonium chloride. The aqueous layer is extracted with ethyl acetate (3×) and the extracts washed with brine, dried over magnesium sulfate, and concentrated in vacuo. The crude product is purified on silica gel (40% ethyl acetate/hexane) to give 785 mg of the title epoxide. 
     Epoxide 6 
     A mixture of 2-(pyrazol-5-yl)phenol (Catalan, et al.,  J. Am. Chem. Soc.,  114(13):5039-48, 1992, 10 mmol, 1.60 g), triethylamine (40.0 mmol, 5.6 ml), and acetonitrile (55 ml) is cooled in an ice bath under N 2  and treated dropwise with chlorotrimethylsilane (12.0 mmol, 1.52 ml). After the addition is complete, the cold bath is removed and the reaction mixture stirred at ambient temperature for 1 hour. The reaction mixture is then treated with trityl chloride (10.0 mmol, 2.78 g) and stirred at ambient temperature overnight, followed by refluxing for 1 hour. The reaction mixture is concentrated, treated with saturated aqueous sodium bicarbonate, and extracted with ethyl acetate (3×50 ml). The extracts are dried over magnesium sulfate and concentrated to a viscous oil. The oil is crystallized from 20% ethyl acetate/hexane to give 1.72 g of N-trityl-2-(pyrazol-5-yl)phenol. 
     A solution of this intermediate phenol (4.27 mmol, 1.72 g) is reacted with (2S)-glycidyl 3-nitrobenzenesulfonate (4.27 mmol, 1.11 g) substantially as decribed for epoxide 2 except that the present reaction is refluxed for 48 hours and the crude product is purified via crystallization from ethyl acetate to give 860 mg of the title epoxide. 
     Epoxide 7 
     Phenylhydrazine (476 mmol, 51.5 g) and 2-hydroxyacetophenone (476 mmol, 64.8 g) are stirred under reflux in dry ethanol (280 ml) for 6 hours. After cooling, the crystals are filtered off, washed with cold ethanol and dried under vacuum at 50° C. to yield 73 g (68%) of the hydrazone, which is then mixed with nickel chloride (7 g) and heated under a nitrogen atmosphere to 240° C. for 3 hours. After cooling, the mixture is suspended in dichloromethane (800 ml), salt is removed by filtration and the filtrate is concentrated. The resulting crystals are filtered off, washed with dichloromethane (50 ml) and dried in vacuo at 40° C. to give 16.1 g of 2-(2-indolyl)phenol (24%).

Res.,  52(3):561-5, 1974;  J. Med. Chem.,  43(16):3168-3185, 2000;  Bioorg. Med. Chem. Lett.,  10(5):415-418, 2000; and JP 08311060. 
     Epoxide 73 
     A 25 ml 1-propanol solution of 2-methoxyphenyl boronic acid (1.2 g, 7.5 mmol) and 5-bromothien-2-ylsulfonamide (1.2 g, 5 mmol) is stirred under N 2  at room temperature. Palladium(II) acetate (56 mg, 0.25 mmol), triphenylphosphine (200 mg, 0.75 mmol), 2M aqueous Na 2 CO 3  (3 ml, 6 mmol), and 7 ml H 2 O are added and the resulting mixture is refluxed (˜88° C.) for 1 hour. The reaction is cooled, diluted with ethyl acetate, washed with brine, and the brine back extracted with ethyl acetate. The extracts are combined, washed with aqueous NaHCO 3 , brine, dried (Na 2 SO 4 ), filtered, and the filtrate is concentrated. The residue is purified by chromatography (SiO 2 , ethyl acetate/hexane gradient) to give 943 mg (70%) of 5-(2-methoxyphenyl)thiophene-2-sulfonamide. 
     A 70 ml CH 2 Cl 2  suspension of 5-(2-methoxyphenyl)thiophene-2-sulfonamide (1.0 g, 3.7 mmol) is stirred under N 2  at −75° C. as boron tribromide (1.1 ml, 12 mmol) is syringed into the reaction mixture. The amber solution is stirred for 30 minutes at −75° C., then at 0° C. for 2-3 hours. The reaction is quenched with ice, extracted with CH 2 Cl 2 . The extracts are washed with brine, dried (Na 2 SO 4 ), filtered, and the filtrate is concentrated. The residue is purified by chromatography (SiO 2 , ethyl acetate/hexane gradient) to give 720 mg of 5-(2-hydroxyphenyl)thiophene-2-sulfonamide (76%). 
     5-(2-Hydroxyphenyl)thiophene-2-sulfonic acid amide (1.8 g, 7.1 mmol), K 2 CO 3  (1.1 g, 8.5 mmol), and (2S)-glycidyl 3-nitrobenzenesulfonate (2.1 g, 7.8 mmol) are reacted as described for the preparation of Epoxide 1 to give 1.5 g of the title epoxide (70%). 
     Epoxide 74 
     (2-Methoxyphenyl)acetaldehyde is prepared by oxidation of 2-(2-methoxyphenyl)ethanol according to the procedure disclosed in  J. Org. Chem.,  49:1720, 1999. A mixture of (2-methoxyphenyl)acetaldehyde (3.8 g, 25.3 mmol) and dimethylformamide dimethyl acetal (4.52 g, 37.9 mmol) is stirred at room temperature for 1 hour. Excess of the acetal is removed under reduced pressure to leave 4.68 g of 3-dimethylamino-2-(2-methoxyphenyl)propenal (90%). 
     A solution of 3-dimethylamino-2-(2-methoxyphenyl)propenal (4.68 g, 22.8 mmol) and hydrazine hydrate (6.7 ml) in ethanol (100 ml) is heated at reflux for 30 minutes. The solvent is removed in vacuo and the residue is chromatographed (silica gel, dichloromethane/ethanol 95:5) to give 2.69 g of 4-(2-methoxyphenyl)pyrazole (68%). 
     To a solution of 4-(2-methoxyphenyl)pyrazole (300 mg, 1.72 mmol) in dichloromethane (13 ml) is added a 1M solution of boron tribromide (3.8 ml) in dichloromethane. The mixture is stirred at room temperature over night then concentrated under reduced pressure. The residue is chromatographed (silica gel, dichloromethane/ethanol 9:1) to give 270 mg of 2-(pyrazol-4-yl)phenol (98%). 
     2-(Pyrazol-4-yl)phenol and (2S)-glycidyl 3-nitrobenzenesulfonate are reacted as described for the preparation of Epoxide 1 to give 180 mg of the title epoxide (50%).

     Representative Procedure 1: Preparation of Aryl Halides 
     (2S)-1-(2-iodophenyloxy)-2,3-epoxypropane (Epoxide 22, 8 mmol) or (2S)-1-(2-iodo-6-fluorophenyloxy)-2,3-epoxypropane (Epoxide 55) is reacted with an equimolar amount of an amine of formula III (Amines 2-5, 9, 10, 12, 31, 36 or 40) in 100 ml of refluxing dry ethanol overnight. After evaporation of the solvent the residue is purified via flash chromatography on silica gel using a dichloromethane-dichloromethane/ethanolic ammonia gradient (100 to 95:5).

     EXAMPLES 
     Representative Procedure 2: Amination of Epoxide 
     A vial is charged with a solution of single amine of formula III (0.2M in ethanol or t-butanol, 90 micromolar) and a solution of a single epoxide of formula II (0.2M in dimethylsulfoxide, 80 micromolar). The vial is sealed and heated to 80° C. for 24-48 hours. The solution is cooled to room temperature, diluted with methanol, and passed over a cation exchange column, eluting the basic material with 1N methanolic ammonia. 
     Representative Procedure 3: Amination of Epoxide 
     A stirred mixture of an epoxide of formula II (1 equivalent) and an amine of formula III (1-2 equivalents) in ethanol, methanol, n-butanol or t-butanol is heated at 70-80° C. for 2-72 hours. The solvent is evaporated to dryness to give a crude oil that is optionally diluted with methanol or ethanol and passed over a cation exchange column (eluting the free base product with 1N methanolic ammonia) before further purification. 
     The final products prepared via Representative Procedure 2 or 3 may be further purified by flash or radial chromatography. Typical chromatography conditions include: a) using a variable mixture of 25:5:1 chloroform/methanol/ammonium hydroxide and 9:1 chloroform/methanol; b) a variable mixture of 90:10:1 CH 2 Cl 2 /ethanolic NH 3  gradient; c) dichloromethane/6-12% methanol, 0.15-0.35M ammonia in dichloromethane gradient; d) methylene chloride with a step gradient to 2-8% methanol; e) chloroform/2.0M ammonia in methanol, from 0-10% to 6-20% gradient elution or f) isocratic 6-8% 2M ammonia in methanol: 92-94% dichloromethane. 
     Alternatively, the final products may be purified on C18 bonded silica gel using either mass guided or UV guided reverse phase liquid chromatography (acetonitrile/water with 0.01% hydrochloric acid or 0.1% trifluoroacetic acid). When purification of a compound of the present invention results in production of a free base, the free base thus prepared may be salified, e.g., by dissolution of the free base in CH 2 Cl 2  or diethylether, adding 1M ethanolic HCl or a solution of HCl in diethylether, and evaporating the volatiles, or as described in more detail below. 
     For example, a hydrochloride salt may be prepared by dissolving the free base in dichloromethane, diethylether, or a mixture of ethyl acetate and methanol and adding 1M ethanolic HCl, a solution of HCl in diethylether, or 0.5M ammonium chloride. The resulting mixture is allowed to stir for a short time, e.g., for five minutes, before evaporating the volatiles and optionally triturating in diethyl ether to give the hydrochloride salt. 
     The oxalate salts may be prepared by dissolving the free base in a small amount of ethyl acetate, optionally adding methanol for solubitity. The resulting solution is treated with 1 equivalent of a 0.5M solution of oxalic acid in ethyl acetate. The reaction mixture is either concentrated in vacuo or centrifuged, separated, and the solids are dried, to give the oxalate salt. 
     To prepare a succinate salt, the free base may be dissolved in a small amount of ethyl acetate or methanol and then treated with 1 equivalent of succinic acid in methanol. The resulting slurry is dissolved in the minimum amount of methanol then concentrated in vacuo to give the succinate salt. 
     For products synthesized from Epoxide 6, the crude products are treated with 1N HCl/dioxane for 2 hours at room temperature and concentrated before purifying on C18 bonded silica gel as described above to give a compound of the formula:                           
     For products synthesized from Epoxide 20, the title compounds are prepared by removal of the Boc-protecting group from the imidazoline ring by stirring a solution of the crude protected product in dichloromethane/2N HCl 10:1. 
     For products synthesized from Epoxide 24, the intermediate N,N-dimethylamino-propenones are treated with hydrazine hydrate in ethanol to give a compound of the formula:                           
     The table below sets out representative combinations of Amines and Epoxides that are reacted as described above in Representative Procedure 2 or 3. Preparation of desired product is confirmed via mass spectral analysis (MSA). Emax±Standard Error Mean (SEM) data, discussed in the “Demonstration of Function” section below, is also included for said compounds where available. The Emax values represent the average of at least 3 runs except as otherwise indicated.

     Representative Procedure 4: Suzuki Coupling 
     Procedure 4(a) 
     A compound of formula V (6.4 mmol) is dissolved in 50 ml of dry dioxane and thoroughly flushed with argon. Palladium(0) tetrakis(triphenylphosphine) (750 mg, 0.64 mmol) is added under argon and stirred at ambient temperature until the mixture becomes homogenous. The clear solution is divided into aliquots of 2 ml, and each testing tube is charged with 2 equivalents of an aryl boronic acid of formula IV and 500 μl of 2M aqueous sodium carbonate under argon. The testing tubes are sealed and heated in a microwave oven (MLS ETHOS 1600) for 35 minutes and 100° C. at 1000 W. After complete conversion the samples are diluted with 2 ml of water and extracted with 3 ml of dichloromethane. Extraction is repeated with 2 ml of dichloromethane. The organic solutions are collected and dried over sodium sulfate. The organic filtrate is treated with pre-treated Amberlyst 15 (3 to 4 g each). (Prior to use Amberlyst 15 is prewashed with dichloromethane, ethanol then dichloromethane until the filtrate is colorless). The suspensions are shaken for 30 minutes on an orbital shaker and filtered. The Amberlyst is repeatedly rinsed with dichloromethane/ethanol 1:1 (4×3 ml) and then repeatedly treated with dichloromethane/ethanolic ammonia 1:1. Finally the resin is treated with ethanolic ammonia overnight. The alkaline filtrates are collected and evaporated. 
     Procedure 4(b) 
     A mixture of an aryl halide of formula V (1.2 mmol), a boronic acid of formula IV (2.4 mmol), palladium(0) tetrakis(triphenylphosphine) (0.06 mmol), and 2M aqueous sodium carbonate (1.5 ml) in dioxane (20 ml) is heated over night at 100° C. in a sealed tube. The mixture is poured into water and extracted two times with ethyl acetate. The combined organic layers are washed with brine, dried over sodium sulfate, and concentrated under reduced pressure. 
     The final products prepared via Suzuki coupling may be purified by normal phase chromatography (silica gel, dichloromethane/ethanolic ammonia) providing the free bases or by reverse phase chromatography (acetonitrile/0.1% triflouroacetic acid or 0.01% HCl in water) providing the triflouro acetate or hydrochloride salts. The final products existing as salts may also be prepared in a seperate salification step by dissolution of the free base in ethanol or dichloromethane and treatment of the solution with acid, e.g., 1N ethanolic HCl. Removal of all volatiles reduced pressure, affords the desired salt. 
     The table below sets out representative combinations of aryl halides and boronic acids that are reacted as described above. Preparation of desired product is confirmed via mass spectral analysis (MSA). Emax±Standard Error Mean (SEM) data, discussed in the “Demonstration of Function” section below, is also included for said compounds where available. The Emax values represent the average of at least 3 runs except as otherwise indicated.

     Demonstration of Function 
     The genes encoding the human β 1 -adrenergic receptor (Frielle et al.,  Proc. Natl. Acad. Sci.,  84:7920-7924, 1987), the human β 2 -adrenergic receptor (Kobika et al.,  Proc. Natl. Acad. Sci.,  84:46-50, 1987, Emorine et al.,  Proc. Natl. Acad. Sci.,  84:6995-6999, 1987) and the human β 3  adrenergic receptor (Granneman et al.,  Molecular Pharmacology,  44(2):264-70, 1993) are individually subcloned into a phd expression vector (Grinnell et al.,  Bio/Technology,  5:1189-1192, 1987) and transfected into the DXB-11 Chinese hamster ovary (CHO) cell line by calcium phosphate precipitation methodology. The stably transfected cells are grown to 95% confluency in 95% Dulbecco&#39;s modified Eagles Medium (DMEM), 5% fetal bovine serum and 0.01% proline. Media is removed and the cells are washed with phosphate buffered (pH 7.4) saline (without magnesium and calcium). Cells are then lifted using an enzyme free cell dissociation solution (Specialty Media, Lavallette, N.J.) and pelleted by centrifugation. 
     Cells from each of the above cell lines are resuspended and added (20,000/well) to a 96-well plate. Cells are incubated at 37° C. with representative compounds of the invention for 20 minutes in buffer (Hank&#39;s balanced salt solution, 10 mM HEPES, 0.1% BSA, 1 mM L-ascorbic acid, 0.2% dimethyl sulfoxide, 1 mm 3-isobutyl-1-methylxanthine, pH 7.4). After halting the incubation with quench buffer (50 mM Na Acetate, 0.25% Triton X-100, pH 5.8), the c-AMP level is quantified by scintillation proximity assay (SPA) using a modification of the commercially available c-AMP kit (Amersham, Arlington Heights, Ill.) with rabbit anti-cAMP antibody (ICN Biomedicals, Aurora, Ohio) for the kit. 
     Sigmoidal dose response curves, from the whole cell receptor coupled c-AMP assay are fit to a four parameter logistic equation using non linear regression: y=(a−d)/(1+(Dose/c) b )+d where a and d are responses at zero and maximal dose, b is the slope factor and c is the EC 50  as previously described (DeLean et al.,  Am. J. Physiol.,  235, E97-E102, 1978). EC 50  is assessed as the concentration producing 50% of the maximum response to each agonist. 
     Isoproterenol is accepted in the art as a non-selective β 3  agonist and is widely used as a comparator in evaluating the activity of compounds. See  Trends in Pharm. Sci.,  15:3, 1994. The % intrinsic activity (E max ) of representative compounds of the invention is assessed relative to isoproterenol by the compound&#39;s maximal response divided by the isoproterenol maximal response times 100. 
     In vitro Rat Atrial Tachycardia 
     Male rats (250-350 g) (Harlan Sprague Dawley, Indianapolis, Ind., USA) are killed by cervical dislocation. Hearts are removed and the left and right atria are dissected and mounted with thread in tissue baths containing 10 mls of modified Krebs&#39; solution. Initial resting tension is 1.5-2.0 g at the outset of the experiment ( Naunyn - Schmied Arch. Pharmacol.,  320:145, 1982). Tissues are allowed to equilibrate approximately 30 minutes with vigorous oxygenation before exposure to a compound of the invention. 
     To evaluate the ability of test compounds to increase heart rate, representative compounds of the present invention are added cumulatively once the atrial rate reached a steady state from the previous addition. Compound addition is continued until no further increase in atrial rate occurred or until a concentration of 10 −4 M is reached. The increase in beats per minute (bpm) is measured for each concentration of test compound by means of a BioPac System ( Br. J. of Pharmacol.,  126:1018-1024, 1999).

     The solution of the above ingredients is intravenously administered to a patient at a rate of about 1 ml per minute. 
     Dose 
     The specific dose administered is determined by the particular circumstances surrounding each situation. These circumstances include, the route of administration, the prior medical history of the recipient, the pathological condition or symptom being treated, the severity of the condition/symptom being treated, and the age and sex of the recipient. However, it will be understood that the therapeutic dosage administered will be determined by the physician in the light of the relevant circumstances. 
     Generally, an effective minimum daily dose of a compound of formula I is about 5, 10, 15, or 20 mg. Typically, an effective maximum dose is about 500, 100, 60, 50, or 40 mg. Most typically, the dose ranges between 15 mg and 60 mg. The exact dose may be determined, in accordance with the standard practice in the medical arts of “dose titrating” the recipient; that is, initially administering a low dose of the compound, and gradually increasing the does until the desired therapeutic effect is observed. 
     Route of Administration 
     The compounds can be administered by a variety of routes including the oral, rectal, transdermal, subcutaneous, topical, intravenous, intramuscular or intranasal routes. 
     Combination Therapy 
     A compound of formula I may be used in combination with other drugs that are used in the treatment/prevention/suppression or amelioration of the diseases or conditions for which compounds of formula I are useful. Such other drug(s) may be administered, by a route and in an amount commonly used therefor, contemporaneously or sequentially with a compound of formula I. When a compound of formula I is used contemporaneously with one or more other drugs, a pharmaceutical unit dosage form containing such other drugs in addition to the compound of formula I is preferred. Accordingly, the pharmaceutical compositions of the present invention include those that also contain one or more other active ingredients, in addition to a compound of formula I. Examples of other active ingredients that may be combined with a compound of formula I, either administered separately or in the same pharmaceutical compositions, include, but are not limited to: 
     (a) insulin sensitizers including (i) PPARγ agonists such as the glitazones (e.g. troglitazone, pioglitazone, englitazone, MCC-555, BRL49653 and the like), and compounds disclosed in WO97/27857, 97/28115, 97/28137 and 97/27847; (ii) biguanides such as metformin and phenformin; 
     (b) insulin or insulin mimetics; 
     (c) sulfonylureas such as tolbutamide and glipizide; 
     (d) alpha-glucosidase inhibitors (such as acarbose); 
     (e) cholesterol lowering agents such as 
     i. HMG-CoA reductase inhibitors (lovastatin, simvastatin and pravastatin, fluvastatin, atorvastatin, and other statins), 
     ii. sequestrants (cholestyramine, colestipol and a dialkylaminoalkyl derivatives of a cross-linked dextran), 
     iii. nicotinyl alcohol nicotinic acid or a salt thereof, 
     iv. proliferator-activator receptor a agonists such as fenofibric acid derivatives (gemfibrozil, clofibrat, fenofibrate and benzafibrate), 
     v. inhibitors of cholesterol absorption for example beta-sitosterol and (acyl CoA:cholesterol acyltransferase) inhibitors for example melinamide, 
     vi. probucol, 
     vii. vitamin E, and 
     viii. thyromimetics; 
     (f) PPARδ agonists such as those disclosed in WO97/28149; 
     (g) antiobesity compounds such as fenfluramine, dexfenfluramine, phentermine, sibutramine, orlistat, and other β 3  adrenergic receptor agonists; 
     (h) feeding behavior modifying agents such as neuropeptide Y antagonists (e.g. neuropeptide Y5) such as those disclosed in WO 97/19682, WO 97/20820, WO 97/20821, WO 97/20822 and WO 97/20823; 
     (i) PPARα agonists such as described in WO 97/36579 by Glaxo; 
     (j) PPARγ antagonists as described in WO97/10813; and 
     (k) serotonin reuptake inhibitors such as fluoxetine and sertraline.
