Description: NOVEL BIARYL ETHER DERIVATIVES USEFUL AS MONOAMINE REUPTAKE INHIBITORS Background of the Invention Serotonin Selective Reuptake Inhibitors (SSRIs) currently provide efficacy in the treatment of major depressive disorder (MDD) and are generally perceived by psychiatrists and primary care physicians as effective, well-tolerated and easily administered However, they are associated with undesirable features, such as reports of sexual dysfunction, delayed onset of action and a level of non-responsiveness estimated to be as high as 30% (see M J Gitlin, Journal of Clinical Psychiatry, 1994, 55, 406-413 and R T Segraves, Journal of Clinical Psychiatry, 1992, 10(2), 4-10) Prechnical and clinical evidence has indicated that the sexual dysfunction associated with SSRI therapy can be reduced through the use of dopamme reuptake inhibitors (DRIs), such as bupropion (see A K Ashton, Journal of Clinical Psychiatry, 1998, 59(3), 112-1 15) Furthermore, the combination of SRI and DRI may hasten the onset of action as well as offering relief to refractory patients, possibly through a synergistic mechanism (see R D Marshall et al, Journal of Psychopharmacology, 1995, 9(3), 284-286) and prove beneficial in the treatment of substance abuse and attention deficit hyperactivity disorder (ADHD) according to Barπckman et al, Journal of the American Academy of Child and Adolescent Psychology, 1995, 34(5), 649 and Shekim et al, Journal of Nervous and Mental Disease, 1989, 177(5), 296 This invention relates to novel biaryl ether derivatives that exhibit activity as monoamine (e g , dopamme, serotonin) reuptake inhibitors, to pharmaceutical compositions containing such compounds and to methods of using such compounds to treat central nervous system (CNS) and other disorders United States Patent 4,018,830, issued April 19, 1997, refers to phenylthioaralkylamines and 2-phenylthιobenzylamιnes which are active as antiarrhythmics WO 97/17325, International

compounds of the formula XVIIl wherein X, Z, Y, n, and m are defined as above and Q is -C(=0)R 3 or cyano and R 3 is H, d-C 4 alkyl, OH, 0-(C C 6 )alkyl or NR 1 R 2 , wherein R and R 2 are selected, independently, from hydrogen and (d-C 4 )alkyl, or R 1 and R 2 , together with the nitrogen to which they are attached, form a four to eight membered saturated ring containing one or two heteroatoms, including the nitrogen to which R 1 and R 2 are attached, wherein the second heteroatom, when present, is selected from oxygen, nitrogen and sulfur Compounds of formula XVIIl are useful as intermediates for preparing compounds of formula I The compounds of formula XVIIl may have optical centers and therefore may occur in different enantiomeπc configurations The invention includes all enantiomers, diastereomers, and other stereoisomers of such compounds of formula XVIIl, as well as racemic and other mixtures thereof The invention also includes tautomers of compounds of formula

Unless otherwise indicated, A, B, Q, R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , X, Y, Z, m and n, and structural formulas I and XVIIl, in the reaction schemes and discussion that follows are as defined above SCHEME 1 lllb Ha Ilia lib V (XVIIl) SCHEME 2 H, C,-C 4 alkyl X SCHEME 3 Xlla W = J IVW = J Xllb W = X vw = x SCHEME 4 V, R 3 = O-alkyl XXI (XVIII) XXIII XXII SCHEME5 Scheme 1 refers to the preparation of compounds of the formula I from compounds of the formulae II and III. L represents a suitable leaving group such as flouro, chloro, nitro, or triflate. In scheme 1 , Z is hydrogen. However, using the appropriate starting compound of formula II, compounds of formula I wherein Z is other than hydrogen can be prepared according to the same scheme. Compounds of the formulas lla, lib, Ilia and 1Mb are commercially available or can be made by methods well known to those of ordinary skill in the art. For example, compounds of general formulas lla and lib wherein R is H may be prepared by introducing an aldehyde functional group (CHO) to a compound of formula XV or XVI, respectively, using methods well known to those of skill in the art. XV XVI When L = F, the procedure of A. J. Bridges et al.. Tetrahedron Letters, 1992, 33(49), 7499-7502, is particularly useful for the synthesis of substituted ortho-fluorobenzaldehydes. Other such transformations have been described by C. F. H. Allen et al., Organic Synthesis, 1951 , 31 , 92, T. DePaulis et al, Journal of Medicinal Chemistry, 1986, 29, 61 ; I. M. Godfrey et al., J. Chemical Society, Perkin Transactions 1 , 1974, 1353; K. M. Tramposil et al., Journal of Medicinal Chemistry, 1983, 26(2), 121 ; and M. E. Cracknell et al., Chemistry and Industry, (London), 1985, (9), 309. Referring to Scheme 1 , a compound (i.e., an aldehyde or ketone) of the formula lla is reacted with a compound (i.e., a phenol) of the formula Ilia in the presence of a base to form the corresponding compound of formula IV. This reaction is generally carried out at a temperature from about 0°C to about 150°C for about 1 hour to about 3 days, preferably at about 90-95°C for about 18 hours, in a polar solvent such as dimethyl sulfoxide (DMSO), N,N- dimethylformamide (DMF), N,N-dιmethylacetamide (DMA) or N-methyl-2-pyrrolidinone (NMP), preferably DMF. Suitable bases include anhydrous sodium carbonate (Na 2 C0 3 ), potassium carbonate (K 2 C0 3 ), sodium hydroxide (NaOH), potassium hydroxide (KOH) and amines such as pyrrolidine, tπethylamine and pyndine, with anhydrous K 2 C0 3 being preferred. Details for conducting this procedure can be found in G W. Yeager et al., Synthesis, 1995, 28-30; J. R. Dimmock et al., Journal of Medicinal Chemistry, 1996, 39(20), 3984-3997. Alternatively, phenols of the formula Mb and compounds of the formula lllb may be converted into aldehydes or ketones of the general formulae IV according to the procedures described by K. Tomisawa et al., Chemical and Pharmaceutical Bulletin, 1984, 32(8), 3066-3074. Next, a compound of the formula IV, wherein J is a leaving group, for example bromine, iodine, tπflate, fluorosulfonate or methanesulfonate, can be converted to a compound of the formula V by reaction with a compound of the general formula X-G, wherein G is defined as a reactive leaving group such as B(OH) 2 , Sn[(C 1 -C 6 )alkyl], Zn(Hal) and the like, usually in the presence of a catalytic amount of a catalyst, e g , tetrakιs(trιphenylphosphιne) palladιum(O), tetrakιs(tπphenylphosphιne) nιckel(O) or dιchlorobιs(trιphenylphosphιne) palladιum(ll), among others, and in the presence of a base such as sodium carbonate, potassium carbonate or tπethylamine The reactions can be conducted in a variety of organic solvents (e g , benzene, dimethoxyethane) or in mixtures such as aqueous N,N-dιmethylformamιde or aqueous ethanol at temperatures in the range of about 0 °C to about 100 °C A good general reference for this process may be found in the review by Stephen Stanforth, Tetrahedron, 1998, 54, 263-303 Other specific references include M J Sharp et al, Synthetic Communications, 1981 , 11 (7), 513, R B Miller et al, Tetrahedron Letters, 1989, 30(3), 297, W J Thompson et al, Journal of Organic Chemistry, 1984, 49(26), 5237 The compounds of the general formula X-G are in many cases commercially available or can be prepared by one skilled in the art of organic synthesis (for example, see the procedures in M J Sharp and V Snieckus, Tetrahedron Letters, 1985, 26(49), 5997-6000, G W Kabalka et al, Journal of Organometallic Chemistry, 1983, 259, 269-274) Alternatively, an intermediate of the formula lla may be converted into a compound of the formula He, wherein X is as defined above, using the methods described above for the conversion of compounds of formula IV to V These intermediates of formula He can then be reacted with a compound of the general formula Ilia to produce the ethers of general formula V using the methods described above for the conversion of compounds of formula lla to IV Additionally, compounds of formulae lla or IV, wherein J is a functional group like CN, can be converted to compounds of the formula lie or V wherein X is a moiety such as and wherein R 10 is independently chosen from hydrogen, (C 1 -C 6 )alkyl, aryl-(d-C 6 )alkyl or aryl, optionally substituted with hydrogen, halo, (d-C 6 )alkyl, (d-C 6 )alkoxyl or (d-C 6 )SO r , where r is zero, one or two Methods for this conversion are well documented in the chemical literature, for example, through the use of sodium azide and lithium chloride in 2- methoxyethanol according to the procedure described by J Sauer et al, Tetrahedron, 1960, 11 , 241 Under these conditions, it may be necessary to initially protect the COR 3 group of compound lla or IV to effectively convert the J group to the corresponding group X of compounds lie or V (intermediates of formula XVIIl), respectively. There are many protecting groups available which can be utilized in this process, including acetals and ketals which are described and referenced by P. G. M. Wuts and T. W. Green in Protective Groups in Organic Synthesis, 2 nd ed., John Wiley and Sons, New York, 1991 , pp 175-223. The selection of an appropriate protecting group can be made based upon the presence of other reactive groups in the molecule. Subsequently, compounds of the formula V (R 3 = H or (Cι-C 4 )alkyl) can be converted into compounds of the formula I by subjecting them to reductive amination conditions. For example, a compound of the formula V can be reacted with a compound of the formula ,1 D 2 . HNR R to form an intermediate of the formula XVII: which may be isolated or converted directly in the same reaction step into a compound of the formula I. This conversion, whether in situ or starting with the isolated compound of formula XVII, can be performed using one or more methods known to those skilled in the art. For example, the compound of formula V and the appropriate compound of formula HNR 1 R can be combined in the presence of a dehydrating reagent such as titanium (IV) tetrachloride or titanium (IV) isopropoxide, in a reaction inert solvent such as benzene, toluene, ethanol or a like solvent, until the reaction is judged to be complete, according to the procedure of S. Bhattarcharyya (Journal of Organic Chemistry, 1995, 60(15), 4928-4929). Alternatively, the compound of formula V and the compound of formula HNR 1 R 2 can be combined in an inert solvent such as benzene or toluene, in the presence or absence of a water scavenger such as molecular sieves, and heated to eliminate water generated during the formation of the intermediate of formula XVII. The degree of completion of the conversion of compounds of the formula IV into the above intermediate(s) of formula XVII can be assessed using one or more known analytical techniques, including 1 H-NMR spectroscopy. In some instances, it may be possible or desirable to isolate the intermediate(s) of formula XVII, or they may be further reacted with a reducing agent selective for the reduction of the intermediate to the desired compounds of formula I. Such reducing agents are widely known to those skilled in the art and include, for example, sodium borohydnde (NaBH 4 ), sodium cyanoborohydnde (NaBH 3 CN) and sodium triacetoxy-borohydπde (NaBH(OAc) 3 ), as described by A F Abdel-Magid et al in Tetrahedron Letters, 1990, 31 , 5595 This reduction is generally carried out in a polar solvent such as methanol, ethanol, isopropanol or a like solvent, and at temperatures of about 0°C to about 100°C, preferably at room temperature In the procedure described by Bhattarcharyya, the intermediate of formula XVII is formed in an ethanol solvent and, without isolation, is reduced to the product of formula I using NaBH 4 As an alternative to the aldehyde or ketone intermediates of formulae IV and V, one skilled in the art can also prepare compounds of formula VII (i e , nitπles), beginning with compounds of the formulae Ilia and VI, as illustrated in Scheme 2, using the diphenyl ether formation procedure described in Scheme 1 These compounds can then serve as intermediates for the syntheses of the desired compounds of formula I. Procedures for preparation of the compounds of formula VI used in this process can be adapted from those found in the literature (See, e g , D C Remy et al , Journal of Medicinal Chemistry, 1975, 18(2), 142-148, E A Schmittling et al , Journal of Organic Chemistry, 1993, 58(12), 3229- 3230) The conversion of the nitnles of formula VII so obtained into the desireα products of formula I can be achieved by several routes, as depicted in Scheme 2 For example, the nitrile group of VII can be hydrolyzed under acidic conditions using methods well known to those of skill in the art, to produce a carboxylic acid derivative of formula VIII (See, e g , A I Meyers et al , Tetrahedron Letters, 1984, 25 (28), 2941 , and R W Higgins et al , Journal of Organic Chemistry, 1951 , 16, 1275) This carboxylic acid derivative can then be converted to a compound of the formula V (R 3 = OH), using procedures previously described in Scheme 1 for the conversion of IV to V, subsequently compound V (R 3 = OH) can be converted to compound V (R 3 = NR 1 R 2 ) and then to the compounds of formula I as described below Alternatively, compound VIII can be converted into a carboxamide derivative of formula IX using one or more standard methods which are disclosed in the chemical literature, e g , via reaction of an acid halide prepared from a compound of the formula VIM with an amme of general formula HNR 1 R 2 (see R E Kent et al , Organic Synthesis, Coll Vol III, 1955, 490, and R M Herbst et al , Organic Synthesis, Coll, Vol II, 1943, 11 for discussions of the Schotten-Bauman reaction) These carboxamides of formula IX can then be converted to the corresponding carboxamides of formula V (R 3 = NR 1 R 2 ) by replacing the J substituent with the appropriate X group using conditions similar to those described for converting IV to V in Scheme 1 The carboxamides of formulae V so prepared can then be reduced to the final products of formulae I using an appropriate reduction process Depending on the presence of substituents X, Y and Z on the carboxamides V, this reduction can be accomplished using one or more of a variety of reagents including lithium aluminum chloride (e.g., J. Lehmann et al, Archiv Pharm (Weinheim, Ger.), 1982, 315 (11 ), 967; N. S. Narasimhan and P. A. Patil, Journal of the Chemical Society, Chemical Communications, 1987, (3), 191 ), diborane (H. C. Brown et al, Journal of the American Chemical Society, 1970, 92, 1637 and 1973, 38, 912; N. M Moon et al, Journal of Organic Chemistry, 1973, 38, 2786; H. C. Brown and V. Verma, Journal of Organic Chemistry, 1974, 39, 1631 ), thexylborane / diethylanilme (A Pelter et al, Tetrahedron Letters, 1978, 4715), phosphorus trichloride / toluene followed by ethano c sodium borohydπde (A Rahman et al, Tetrahedron Letters, 1976, 219) or aluminum hydride (H C Brown et al, Journal of the American Chemical Society, 1966, 88,1464, A F. Burchat et al, Journal of Organic Chemistry, 1996, 61 (21 ), 7627-7630) The resulting carboxamides of the formula IX, wherein R 1 and R 2 are hydrogen, can also be prepared directly from the corresponding nitnles of formula VII by specific hydrolysis methods, employing, for example, hydrogen peroxide or strong aqueous alkali metal salts (See Chemistry & Industry, 1961 , 1987, C R Noller, Organic Synthesis, Coll Vol. II, 1943, 586, and J H Hall and M Gisler, Journal of Organic Chemistry, 1976, 41 , 3769) Subsequently, the carboxamide derivatives of formula IX may can be converted to the carboxamide compounds of formula V (R 3 = NR 1 R 2 ) in the manner just described for the conversion of VIII to V Finally, the nitnles of formula X, obtained from the nitnles of formula VII analogously to the conversion of compounds of formulae IV to V, can be reduced to the desired compounds of general formula I, wherein R 1 and R 2 are both hydrogen, by using one of a variety of reducing agents disclosed in the chemical literature which are selective for this transformation (including catalytic hydrogenation using hydrogen gas and platinum (II) oxide, as described by J A. Secπst, 111 and M W Logue in Journal of Organic Chemistry, 1972, 37, 335, hydraz e hydrate and Raney nickel in ethanol, as described by W W Zajac, Jr et al in Journal of Organic Chemistry, 1971 , 36, 3539, and sodium tπfiuoroacetoxy borohydnde in THF, as described by N Ummo et al in Tetrahedron Letters, 1976, 2875) Such reducing agents can also include lithium aluminum hydride in a nonreactive solvent such as diethyl ether or tetrahydrofuran (see, e g , A C Cope et al , Organic Synthesis, Coll Vol IV, 1963, 339, for use of lithium aluminum hydride in a diethyl ether or THF solvent) The nitnles of formula VII may also be converted to the corresponding aldehydes of general formula IV, wherein R 3 is hydrogen, using reagents and conditions which are specific for this transformation, such as lithium tπethoxyaluminum hydride in a solvent such as THF or diethyl ether, as described by H C Brown and C P Garg in Journal of the American Chemical Society, 1964, 86, 1085 and by J Malek and M Cerny in Synthesis , 1972, 217 In addition to the methods described above in Schemes 1 and 2 for the preparation of the intermediate aldehydes and ketones of formula I, other methods exist which can provide compounds of the formula I. For example, in the procedure depicted in Scheme 3, a compound of formula Xlla.b, in which E is a hydrogen atom, can be reacted, under conditions of Friedel-Crafts acylation (e.g., to produce ketones of the formula IV or V in which R 3 is d-C 4 alkyl (C. F. H. Allen, Organic Synthesis, Coll. Vol. II, 3, 1943). Alternatively, an acid anhydride, i.e., (R 3 CO) 2 0 can be reacted under similar conditions (O. Grummitt et al, Organic Synthesis, Coll. Vol. Ill, 109, 1955) to produce the intermediate compounds of formula IV or V. When it is desired to prepare compounds of formula IV or V where R 3 is hydrogen, said compound may be prepared from compounds of formula Xlla.b via a Vilsmeier-Haack acylation, using the methods described by E. Campaigne and W. L. Archer, Organic Synthesis, Coll. Vol. IV, 331 , 1963 and by J. H. Wood and R. W. Bost, Organic Synthesis, Coll. Vol. IV, 98, 1955. The location of the acyl group (COR 3 ) introduced in this manner can be determined by the nature and location of the J, X and/or Y substituents present, as well as by the conditions employed for the reaction. In instances where it is desirable to prepare compounds of formula IV (R 3 =H), from Xlla (E=H), introduction of the aldehyde functional group (CHO) can also be achieved using conditions described above for the preparation of the intermediates lla and lib in Scheme 1. For example, preparation of compounds of the formula IV wherein R 3 = H (i.e., aldehydes) can be achieved using one or more of the known procedures for the formylation of aromatic rings, including reacting dichloromethyl methyl ether and titanium (IV) tetrachloride in methylene chloride according to the procedure described by M. L. Mancini et al., Synthetic Communications, 1989, 2001-2007, or H. Chikashita et al., Journal of Organic Chemistry, 1991 , 56, 1692. For the preparation of compounds of the general formula I wherein R 2 and R 3 taken together with the nitrogen to which R 2 is attached and the carbon to which R 3 is attached form a nitrogen containing ring, an adaptation of the procedure described by L. S. Bleicher et al (Journal of Organic Chemistry, 1998, 63, 1 109) can be employed, as shown in Scheme 4. Thus, an ester of the general formula V (R 3 = O-alkyl) (an intermediate of formula XVIIl), prepared by esterification of the corresponding carboxylic acid of formula V (R 3 = OH) (also of formula XVIIl), is reacted with a cyclic lactam of the general formula XXV XXV where L 4 is a reaction labile group such as -CH=CH 2 , in the presence of a strong base such as sodium methoxide, to produce the diketo intermediate of general formula XXI This intermediate can then be converted to the corresponding cyclic imine of formula XXII in the presence of a strong acid, such as hydrochloric acid, usually under reflux conditions Subsequently, the compounds of formula XXII can be reduced to form the cyclic amines of formula XXIII (wherein R 1 = H) using, for example, sodium borohydπde in methanol as described previously Such compounds of formula XXIII can further be converted into compounds of the formula XXIII (wherein R is as defined for compounds of formula I) as previously discussed For the preparation of compounds of general formula I, wherein the group X is a lactam attached to phenyl or naphthyl ring A via the lactam N atom, the method illustrated in Scheme 5 is preferred In this procedure an aldehyde or ketone of general formula IV (R 3 = H or d-C 4 alkyl, respectively) where Q is N0 2 is converted to an amine of the general formula XIX where R 1 is as previously defined, according to the method described in Scheme 1 This intermediate XIX is then converted to a compound of general formula XX, where R 2 is a protecting group, preferably a terf-butoxy-carbonyl (t-BOC) group, that is stable to hydrogenation conditions but can be readily removed at a later point in the synthetic sequence, suggestions for such groups can be found in Wuts and Green, supra, at page 309 This latter intermediate XX wherein Q is N0 2 can then be treated under reduction conditions to form an analogous intermediate of formula XX wherein Q is NH 2 , while leaving the f-BOC group intact Such reduction conditions for this conversion are known to one skilled in the art and include the use of hydrogen gas (H 2 ) and a catalyst, preferably palladium on carbon, in a reaction inert solvent such as a lower alcohol (e g , methanol, ethanol), ester (e g , ethyl acetate), or ether (e g , tetrahydrofuran, 1 ,4-dιoxane) and in the presence or absence of a small amount of acid, preferably a small amount of acetic acid The NH 2 group of the resulting compounds of formula XX can then be converted to cyclic amides (lactams), wherein R 2 remains t-BOC, by reacting them with an omega-chloro alkanoyl chloride or bromide or an omega-bromo alkanoyl chloride or bromide in a neutral solvent such as THF and in the presence of an acid scavenger, such as Na 2 C0 3 , K 2 C0 3 , CS 2 C0 3 or the like, and heating the mixture at the boiling point of the solvent This effects a ring closure forming the cyclic amide (i e lactam) Finally, the protecting group can be removed to obtain the compounds of general formula I wherein X is a lactam and R 2 is H, in the case of the t-BOC protecting group a mixture of ethyl acetate saturated with HCl gas is effective in such removal Pharmaceutically acceptable salts of a compound of formula I can be prepared in a conventional manner by treating a solution or suspension of the corresponding free base or acid with one chemical equivalent of a pharmaceutically acceptable acid or base Conventional concentration or crystallization techniques can be employed to isolate the salts Illustrative of suitable acids are acetic, lactic, succmic, maleic, tartanc, citric, gluconic, ascorbic, benzoic, cmnamic, fumaπc, sulfuric, phosphoric, hydrochloric, hydrobromic, hydroiodic, sulfamic, sulfonic acids such as methanesulfonic, benzene sulfonic, p- toluenesulfonic, and related acids Illustrative bases are sodium, potassium, and calcium A compound of this invention may be administered alone or in combination with pharmaceutically acceptable carriers, in either single or multiple doses Suitable pharmaceutical carriers include inert solid diluents or fillers, sterile aqueous solutions and various organic solvents The pharmaceutical compositions formed by combining a compound of formula I or a pharmaceutically acceptable salt thereof can then be readily administered in a variety of dosage forms such as tablets, powders, lozenges, syrups, mjectable solutions and the like These pharmaceutical compositions can, if desired, contain additional ingredients such as flavorings, binders, excipients and the like Thus, for purposes of oral administration, tablets containing various excipients such as sodium citrate, calcium carbonate and calcium phosphate may be employed along with various dismtegrants such as starch, methylcellulose, algmic acid and certain complex silicates, together with binding agents such as polyvmylpyrrolidone, sucrose, gelatin and acacia Additionally, lubricating agents such as magnesium stearate, sodium lauryl sulfate and talc are often useful for tabletting purposes Solid compositions of a similar type may also be employed as fillers in soft and hard filled gelatin

Beta Plate Model 1205 scintillation counter Determination of the in vivo serotonin reuptake inhibition activity and potency of action for the compounds of the present invention can be made by measuring the ability of the compound to biock the depletion of serotonin in the anterior cortex induced by (+/-)-para- chloroamphetamme (PCA) in the rat, according to a procedure adapted from R W Fuller, H D Snoddy and M L Cohen in Neuropharmacology 23 539-544 (1984) Generally, male, white Sprague-Dawley rats weighing 160-230 g each are assigned to either the control (vehicle) or test groups When the test compound is administered subcutaneously (sc) at a given dose, it is co-administered with 5 mg/kg of para- chloroamphetamme (PCA) Three hours post-dose, the animals are sacrificed by decapitation and the anterior cortices are removed, wrapped in parafilm and frozen in dry ice (-78 C) When dosed orally (po), the rats are fasted the night before the experiment and then treated with the test compound at a given dose 30 minutes prior to the administration of the PCA (5 mg/kg, sc) After three hours, the animals are sacrificed and the tissues removed as above To determine the serotonin (5-HT) levels, the frozen tissues are homogenized with Branson sonifier in 0 5 mL of mobile phase in Eppendorf centrifuge tubes Samples are then spun down at 11000 rpm for twenty minutes in a Sorval SH-MT rotor in a Sorval RC5C centrifuge The supernatant thus obtained is pipetted into HPLC vials and the 5-HT levels are measured on HPLC-EC Interpretation of the results is as follows Each experiment has a set of vehicle treated animals and a set of PCA-only animals The mean 5-HT value of the PCA animals is subtracted from the mean 5-HT value of the vehicle animals This is the signal or window of the response The mean 5-HT value of each test group is determined, the mean of the PCA group subtracted from that, and that amount divided by the window is the per cent protection from the PCA effect for that dose To report an ID 50 , a line is drawn mathematically through the per cent protection values and the 50 per cent level calculated All of the title compounds of formula I in the following Examples were assayed in vitro for serotonin, dopamme, and norepinephnne reuptake inhibition, and all had IC 50 values of about less than or equal to 250 nM for serotonin reuptake inhibition, about less than or equal to 1000 nM for dopamme reuptake inhibition, and about less than or equal to 1000 nM for norepinephnne reuptake inhibition EXAMPLES PREPARATION 1
