Description: Pyrrolidine derivatives- CCR-3 Receptor Antaeonists This invention relates to certain pyrrolidine derivatives that are CCR-3 receptor antagonists, pharmaceutical compositions containing them, methods for their use and methods for preparing these compounds. Tissue eosinophilia is a feature of a number of pathological conditions such as asthma, rhinitis, eczema and parasitic infections ((see Bousquet, J. et al. N. Eng. J. Med. 323: 1033-1039 (1990) and Kay, A.B. and Corrigan, C.J. Br. Med. Bull. 48:51- 64 (1992)). In asthma, eosinophil accumulation and activation are associated with damage to bronchial epithelium and hyperresponsiveness to constrictor mediators. Chemokines such as RANTES, eotaxin and MCP-3 are known to activate eosinophils ((see Baggiolini, M. and Dahinden, CA. Immunol. Today. 15:127-133 (1994), Rot, A. M. et al. J. Exp. Med. 176, 1489-1495 (1992) and Ponath, P.D. et al. J. Clin. Invest., Vol. 97, #3, 604-612 (1996)). However, unlike RANTES and MCP-3 which also induce the migration of other leukocyte cell types, eotaxin is selectively chemotactic for eosinophils ((see Griffith- Johnson, D.A et al. Biochem. Biophy. Res. Commun. 197:1167 (1993) and Jose, P.J. et al. Biochem. Biophy. Res. Commun. 207, 788 (1994)). Specific eosinophil accumulation was observed at the site of administration of eotaxin whether by intradermal or intraperitoneal injection or aerosol inhalation ((see Griffith-Johnson, D.A et al. Biochem. Biophy. Res. Commun. 197:1167 (1993); Jose, P.J. et al. J. Exp. Med. 179, 881-887 (1994); Rothenberg, M.E. et al. J. Exp. Med. 181, 1211 (1995) and Ponath. P.D. J. Clin. Invest., Vol. 97, #3, 604-612 (1996)). Glucocorticoids such as dexamethasone, methprednisolone and hydrocortisone have been used for treating many eosinophil-related disorders, including bronchial asthma ((R. P. Schleimer et. al., Am . Rev. Respir. Dis., 141, 559 (1990)). The glucocorticoids are believed to inhibit IL-5, LL-3 mediated eosinophil survival in these diseases. However, prolonged use of glucocorticoids can lead to side effects such as glaucoma, osteoporosis and growth retardation in the patients ((see Hanania N.A et al., J. Allergy and Clin. Immunol., Vol. 96, 571-579 (1995) and Saha M. T. et al, Acta Paediatrica, Vol. 86, #2, 138-142 (1997)). It is therefore desirable to have an alternative means of treating eosinophil related diseases without incurring these undesirable side effects. Recently, the CCR-3 receptor was identified as a major chemokine receptor that eosinophils use for their response to eotaxin, RANTES and MCP-3. When transfected into a murine pre-β lymphoma line, CCR-3 bound eotaxin, RANTES and MCP-3 and conferred chemotactic responses on these cells to eotaxin, RANTES and MCP-3 ((see Ponath. P.D. et al. J. Exp. Med. 183, 2437-2448 (1996)). The CCR-3 receptor is expressed on the surface of eosinophils, T-cells (subtype Th-2), basophils and mast cells and is highly selective for eotaxin. Studies have shown that pretreatment of eosinophils with an anti-CCR-3 mAb completely inhibits eosinophil chemotaxis to eotaxin, RANTES and MCP-3 ((see Heath H. et al. J. Clin. Invest., Vol. 99, #2, 178-184 (1997)). Blocking the ability of the CCR-3 receptor to bind RANTES, MCP-3 and eotaxin and thereby preventing the recruitment of eosinophils should provide for the treatment of eosinophil-mediated inflammatory diseases. The present invention therefore concerns novel pyrrolidine derivatives which are capable of inhibiting the binding of eotaxin to the CCR-3 receptor and thereby provide a means of combating eosinophil induced diseases, such as asthma.

Compounds that have the same molecular formula but differ in the nature or sequence of bonding of their atoms or the arrangement of their atoms in space are termed "isomers". Isomers that differ in the arrangement of their atoms in space are termed "stereoisomers". Stereoisomers that are not mirror images of one another are termed "diastereomers" and those that are non-superimposable mirror images of each other are termed "enantiomers". When a compound has an asymmetric center, for example, if a carbon atom is bonded to four different groups, a pair of enantiomers is possible. An enantiomer can be characterized by the absolute configuration of its asymmetric center and is described by the R- and 5-sequencing rules of Cahn and Prelog, or by the manner in which the molecule rotates the plane of polarized light and designated as dextrorotatory or levorotatory (i.e., as (+) or (-)-isomers respectively). A chiral compound can exist as either individual enantiomer or as a mixture thereof. A mixture containing equal proportions of the enantiomers is called a "racemic mixture". The compounds of this invention may possess one or more asymmetric centers; such compounds can therefore be produced as individual (R)- or (S)- stereoisomers or as mixtures thereof. For example, if the R 1 substituent in a compound of Formula (I) is alkyl, then the carbon to which it is attached is an asymmetric center and the compound of Formula (I) can exist as an (R)- or (S)- stereoisomer. Unless indicated otherwise, the description or naming of a particular compound in the specification and claims is intended to include both individual enantiomers and mixtures, racemic or otherwise, thereof. The methods for the determination of stereochemistry and the separation of stereoisomers are well-known in the art (see discussion in Chapter 4 of "Advanced Organic Chemistry", 4th edition J. March, John Wiley and Sons, New York, 1992). A "pharmaceutically acceptable excipient" means an excipient that is useful in preparing a pharmaceutical composition that is generally safe, non-toxic and neither biologically nor otherwise undesirable, and includes an excipient that is acceptable for veterinary use as well as human pharmaceutical use. "A pharmaceutically acceptable excipient" as used in the specification and claims includes both one and more than one such excipient. A "pharmaceutically acceptable counterion" means an ion having a charge opposite to that of the substance with which it is associated and that is pharmaceutically acceptable. Representative examples include, but are not limited to, chloride, bromide, iodide, methanesulfonate, p-tolylsulfonate, trifluoroacetate, acetate, and the like. A "pharmaceutically acceptable salt" of a compound means a salt that is pharmaceutically acceptable and that possesses the desired pharmacological activity of the parent compound. Such salts include: (1) acid addition salts, formed with inorganic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, and the like; or formed with organic acids such as acetic acid, propionic acid, hexanoic acid, cyclopentanepropionic acid, glycolic acid, pyruvic acid, lactic acid, malonic acid, succinic acid, malic acid, maleic acid, fumaric acid, tartaric acid, citric acid, benzoic acid, 3-(4-hydroxybenzoyl)benzoic acid, cinnamic acid, mandelic acid, methanesulfonic acid, ethanesulfonic acid, 1,2-ethane-disulfonic acid, 2-hydroxyethanesulfonic acid, benzenesulfonic acid, 4-chlorobenzenesulfonic acid, 2- naphthalenesulfonic acid, 4-toluenesulfonic acid, camphorsulfonic acid, 4-methylbicyclo[2.2.2]oct-2-ene-l-carboxylic acid, glucoheptonic acid, 4,4'-methylenebis-(3-hydroxy-2-ene-l-carboxylic acid), 3-phenylpropionic acid, trimethylacetic acid, tertiary butylacetic acid, lauryl sulfuric acid, gluconic acid, glutamic acid, hydroxynaphthoic acid, salicylic acid, stearic acid, muconic acid, and the like; or (2) salts formed when an acidic proton present in the parent compound either is replaced by a metal ion, e.g., an alkali metal ion, an alkaline earth ion, or an aluminum ion; or coordinates with an organic base such as ethanolamine, diethanolamine, triethanolamine, tromethamine, N-methylglucamine, and the like. "Leaving group" has the meaning conventionally associated with it in synthetic organic chemistry i.e., an atom or group capable of being displaced by a nucleophile and includes halogen, alkanesulfonyloxy, arenesulfonyloxy, ester, or amino such as chloro, bromo, iodo, mesyloxy, tosyloxy, trifluorosulfonyloxy, methoxy, N,O-dimethylhydroxylamino, and the like. "Pro-drugs" means any compound which releases an active parent drug according to Formula (I) in vivo when such prodrug is administered to a mammalian subject. Prodrugs of a compound of Formula (I) are prepared by modifying functional groups present in the compound of Formula (I) in such a way that the modifications may be cleaved in vivo to release the parent compound. Prodrugs include compounds of Formula (I) wherein a hydroxy, sulfhydryl or amino group in compound (I) is bonded to any group that may be cleaved in vivo to regenerate the free hydroxyl, amino, or sulfhydryl group, respectively. Examples of prodrugs include, but are not limited to esters (e.g., acetate, formate, and benzoate derivatives), carbamates (e.g., N,N-dimethylaminocarbonyl) of hydroxy functional groups in compounds of Formula (I), and the like. "Treating" or "treatment" of a disease includes: (1) preventing the disease, i.e. causing the clinical symptoms of the disease not to develop in a mammal that may be exposed to or predisposed to the disease but does not yet experience or display symptoms of the disease, (2) inhibiting the disease, i.e., arresting or reducing the development of the disease or its clinical symptoms, or (3) relieving the disease, i.e., causing regression of the disease or its clinical symptoms. A "therapeutically effective amount" means the amount of a compound that, when administered to a mammal for treating a disease, is sufficient to effect such treatment for the disease.

The compounds of the invention are CCR-3 receptor antagonists and inhibit eosinophil recruitment by CCR-3 chemokines such as RANTES, eotaxin, MCP-2, MCP-3 and MCP-4.

The CCR-3 antagonistic activity of the compounds of this invention was measured by in vitro assays such as ligand binding and chemotaxis assays as described in more detail in Examples 14, 15 and 16. In vivo activity was assayed in the Ovalbumin induced Asthma in Balb/c Mice Model as described in more detail in Example 17. In general, the compounds of this invention will be administered in a therapeutically effective amount by any of the accepted modes of administration for agents that serve similar utilities. The actual amount of the compound of this invention, i.e., the active ingredient, will depend upon numerous factors such as the severity of the disease to be treated, the age and relative health of the subject, the potency of the compound used, the route and form of administration, and other factors. Therapeutically effective amounts of compounds of Formula (I) may range from approximately 0.01-20 mg per kilogram body weight of the recipient per day; preferably about 0.1-10 mg/kg/day. Thus, for administration to a 70 kg person, the dosage range would most preferably be about 7 mg to 0.7 g per day. In general, compounds of this invention will be administered as pharmaceutical compositions by any one of the following routes: oral, inhalation (e.g., intranasal or oral inhalation) or parenteral (e.g., intramuscular, intravenous or subcutaneous) administration. A preferred manner of administration is oral using a convenient daily dosage regimen which can be adjusted according to the degree of affliction. Compositions can take the form of tablets, pills, capsules, semisolids, powders, sustained release formulations, solutions, suspensions, liposomes, elixirs, or any other appropriate compositions. Another preferred manner for administering compounds of this invention is inhalation. This is an effective means for delivering a therapeutic agent directly to the respiratory tract for the treatment of diseases such as asthma and other similar or related respiratory tract disorders (see U. S. Patent 5,607,915). The choice of formulation depends on various factors such as the mode of drug administration and the bioavailability of the drug substance. For delivery via inhalation the compound can be formulated as liquid solutions or suspensions, aerosol propellants or dry powder and loaded into a suitable dispenser for administration. There are three types of pharmaceutical inhalation devices- nebulizer inhalers, metered-dose inhalers (MDI) and dry powder inhalers (DPI). Nebulizer devices produce a stream of high velocity air that causes the therapeutic agents (which has been formulated in a liquid form) to spray as a mist which is carried into the patient's respiratory tract. MDFs typically have the formulation packaged with a compressed gas. Upon actuation, the device discharges a measured amount of therapeutic agent by compressed gas, thus affording a reliable method of administering a set amount of agent. DPFs administer therapeutic agents in the form of a free flowing powder that can be dispersed in the patient's inspiratory air-stream during breathing by the device. In order to achieve a free flowing powder, the therapeutic agent is formulated with an excipient, such as lactose. A measured amount of the therapeutic is stored in a capsule form and is dispensed to the patient with each actuation. Recently, pharmaceutical formulations have been developed especially for drugs that show poor bioavailability based upon the principle that bioavailability can be increased by increasing the surface area i.e., decreasing particle size. For example, U.S. Pat. No. 4,107,288 describes a pharmaceutical formulation having particles in the size range from 10 to 1,000 nm in which the active material is supported on a crosslinked matrix of macromolecules. U.S. Pat. No. 5,145,684 describes the production of a pharmaceutical formulation in which the drug substance is pulverized to nanoparticles (average particle size of 400 nm) in the presence of a surface modifier and then dispersed in a liquid medium to give a pharmaceutical formulation that exhibits remarkably high bioavailability. The compositions are comprised of in general, a compound of Formula (I) in combination with at least one pharmaceutically acceptable excipient. Acceptable excipients are non-toxic, aid administration, and do not adversely affect the therapeutic benefit of the compound of Formula (I). Such excipient may be any solid, liquid, semi- solid or, in the case of an aerosol composition, gaseous excipient that is generally available to one of skill in the art. Solid pharmaceutical excipients include starch, cellulose, talc, glucose, lactose, sucrose, gelatin, malt, rice, flour, chalk, silica gel, magnesium stearate, sodium stearate, glycerol monostearate, sodium chloride, dried skim milk and the like. Liquid and semisolid excipients may be selected from glycerol, propylene glycol, water, ethanol and various oils, including those of petroleum, animal, vegetable or synthetic origin, e.g., peanut oil, soybean oil, mineral oil, sesame oil, etc. Preferred liquid carriers, particularly for injectable solutions, include water, saline, aqueous dextrose, and glycols. Compressed gases may be used to disperse a compound of this invention in aerosol form. Inert gases suitable for this purpose are nitrogen, carbon dioxide, etc. For liposomal formulations of the drug for parenteral or oral delivery the drug and the lipids are dissolved in a suitable organic solvent e.g. tert-butanol, cyclohexane (1% ethanol). The solution is lypholized and the lipid mixture is suspended in an aqueous buffer an allowed to form a liposome. If necessary, the liposome size can be reduced by sonification. (see., Frank Szoka, Jr. and Demetrios Papahadjopoulos, "Comparative Properties and Methods of Preparation of Lipid Vesicles (Liposomes)", Ann. Rev. Biophys. Bioeng., 9:467-508 (1980), and D.D. Lasic, "Novel Applications of Liposomes", Trends in Biotech., 16:467-608, (1998)) Other suitable pharmaceutical excipients and their formulations are described in Remington's Pharmaceutical Sciences, edited by E. W. Martin (Mack Publishing Company, 18th ed., 1990). The level of the compound in a formulation can vary within the full range employed by those skilled in the art. Typically, the formulation will contain, on a weight percent (wt%) basis, from about 0.01-99.99 wt% of a compound of Formula (I) based on the total formulation, with the balance being one or more suitable pharmaceutical excipients. Preferably, the compound is present at a level of about 1-80 wt%. Representative pharmaceutical formulations containing a compound of Formula (I) are described in Example 13. EXAMPLES Example 1 Synthesis of 3-(R5)-aminomethyl-l-tert-butoxycarbonylpyrrolidine Step 1 Melted dimethyl itaconate (150 g, 0.95 mol) was added to an anhydrous solution of ammonia in methanol (7 M, 1000 mL, 7 mol) at room temperature. The reaction vessel was sealed with parafilm and vented with a needle. The solution was left to stand for 3 days, after which the solid was filtered and washed with cold methanol and dried under vacuum to yield pure 4-aminocarbonylpyrrolidin-2-one (150 g)- Step 2 To a stirred slurry of 4-aminocarbonylpyrrolidin-2-one (20 g, 156 mmol) in (100 mL) of cold (0 °C) dry tetrahydrofuran, in a 1L flask under N 2 , was added a solution of lithium aluminum hydride (12 g, 0.32 mmol) in dry tetrahydrofuran (350 mL) dropwise. Once addition was complete and hydrogen evolution had abated, the cooling bath was removed and the reaction mixture was heated at reflux temperature. After the reaction was complete, the reaction mixture was allowed to cool to room temperature and ether (300 mL) was added. Sufficient saturated Na 2 SO was added dropwise over 1 h to destroy excess hydride. Excess water was avoided so as to prevent two phases forming, as the diamine is highly water-soluble. The suspension was filtered over celite with copious washings with tetrahydrofuran and 15% methanol in tetrahydrofuran. The combined washings were concentrated on the rotovap and the pungent residue distilled under vacuum to yield pure 3-(RS)-aminomethylpyrrolidine as a colorless mobile oil (7.6 g). Step 3 Benzaldehyde (5.3 g, 50 mmol) was added to a solution of 3-aminomethyl- pyrrolidine (5.0 g, 50 mmol) in toluene (anhydrous, 100 mL) in a 250 mL flask at room temperature under N 2 . A Dean-Stark apparatus and condenser were fitted and the reaction mixture was heated at reflux for 4 h. The reaction mixture was cooled to room temperature and di-tert-butyldicarbonate (5.3 g, 50 mmol) was added portion- wise and the resulting solution is stirred at room temperature overnight. The reaction mixture was concentrated on the rotavap and the residue was diluted with 1 M NaHSO (80 L, 80 mmol, 1.6 equiv.) and stirred vigorously for 2 h. The reaction mixture was washed with ether to remove unwanted organic byproducts, then basified with 1 M NaOH to pH 7. Further extraction with either ether or ethyl acetate removed additional unwanted byproducts. The aqueous solution was then made strongly basic (pH 12) with 1 M NaOH and extracted with ethyl acetate. The organic layer was washed with brine, dried with Na 2 SO , then concentrated to give the 3-(RS)- aminomethyl-1-tert-butoxycarbonyl-pyrrolidine as a colorless oil (80-90 %), which was used directly without further purification. Example 2 Synthesis of 3-(5)-aminomethyl-l-tert-butoxycarbonylpyrrolidine Step 1 (S)-pyrrolidinol (30g, 0.34 mol) was dissolved in a mixture of water/dioxane (400 mL/300 mL) and NN-diisopropylethylamine (120 mL, 0.69 mol, 2 equiv.) was added. This reaction mixture was cooled to 0°C and di-tert-butyldicarbonate (90 g, 0.41 mol, 1.2 equiv.) in solution in dioxane ( 100 mL) was added slowly. The resulting mixture was stirred at 0°C for 1 h then at room temperature for 8 h. The reaction mixture was then partitioned between diethyl ether and water. The aqueous phase was acidified to pH 3.0 with 1 M HCl and extracted with ethyl acetate. The organic phases were combined and washed with a brine solution. The resulting organic layer was dried over magnesium sulfate, filtered and concentrated to give, after purification by flash chromatography (methanol/CH 2 Cl 2 '. 15/85) (5)- l-(/ert-butoxycarbonylamino)-3- hydroxypyrrolidine as a white solid (40 g). Step 2 (5)-l-(tert-Butoxycarbonyiamino)-3-hydroxypyrrolidine (40 g, 0.21 mol) was dissolved in anhydrous methylene chloride (400 mL), in the presence of N,N- diisopropyl-ethylamine (73 mL, 0.42 mol, 2 equiv.) and cooled using an ice bath. This solution was treated with methanesulfonyl chloride (18 mL, 0.23 mol, 1.1 equiv.) over a 30 min. period and was then allowed to stir at room temperature for 4 h. The solution was concentrated and the residue dissolved in ethyl acetate (250 mL). The resulting organic solution washed with 5 % ΝaHCO 3 and then with brine. The organic extract was dried over magnesium sulfate, filtered and concentrated to give (S)-l-(tert- butoxycarbonyl-amino)-3-methanesulfonyloxypyrrolidine as a dark oil (39 g) which was used directly without further purification. Step 3 (5)-l-(tert-Butoxycarbonylamino)-3-methanesulfonyloxypyrrolidine (39 g, 0.15 mol) was dissolved in acetonitrile (250 mL) and tetra-«-butylammonium cyanide (75 g, 0.28 mol, 1.9 equiv.) was added. The resulting mixture was heated at 65°C for 6 h and then cooled to room temperature. Saturated NaHCO 3 (500 mL) was added and the reaction mixture extracted with toluene (750 mL and 300 mL). The combined organic layers were washed with water and concentrated under reduced pressure to give a brown oil. This crude material was purified by flash chromatography with 20 % ethyl acetate in hexane to give (5)- l-(/ert-butoxycarbonylamino)-3-cyanopyrrolidine as a yellow oil ( 13.5 g). Step 4 A solution of (S)- l-(tc'rt-butoxycarbonylamino)-3-cyanopyrrolidine (13.5g, 67 mmol) in 50 mL of 3 % NH 4 OH/mcthanol and Rancy Nickel (0.5 g, 50 % slurry in water) was pressurized to 40 psi under H 2 atmosphere. After stirring for 12 h at room temperature, the reaction mixture was filtered through a pad of Celite and the residue was washed with 100 mL of methanol. The filtrate was concentrated to dryness to give an oil (5)-l-(tert-butoxycarbonylamino)-3-aminomethylpyrrolidine (10 g). Proceeding as described above, but substituting (S)-pyrrolidinol (1) with (R)- pyiTolidinol (1) gave (R)-l-(terr-butoxycarbonylamino)-3-aminomethylpyrrolidine. Example 3 Synthesis of 3-(RS)-aminomethyl-l-(3,4-dichlorobenzyl)pyrrolidine Step 1 Neat 3,4-dichlorobenzylamine (18 g, 1 14 mmol) was added to a solution of dimethyl itaconate (20 g, 1 14 mmol) in methanol (200 mL) at room temperature. The solution was stirred at for 48 h then concentrated in vacuo. The resulting solid was divided equally into two, one portion being treated with methanolic ammonia (7 M, 300 mL, 2.1 mol). The solution was vented with a needle and allowed to stand for 2 days. The slurry of solvent and product was concentrated further and filtered. The filter cake was washed with cold methanol to give pure 3-aminocarbonyl- l-(3,4- dichlorobenzyl)-pyrroIidin-2-onc ( 18.5 g). Step 2 A suspension of 3-aminocarbonyl-l-(3,4-dichlorobenzyl)pyrrolidin-2-one in dry tetrahydrofuran (150 mL) was added slowly to a solution of lithium aluminum hydride (4.9 g, 128 mmol, 2 equiv.) in tetrahydrofuran (100 mL) under N 2 at room temperature. The reaction mixture was heated at reflux overnight, diluted with ether, and quenched with brine. After 1 h of rapid stirring, the gray mixture was filtered through celite (ethyl acetate washings) and the filtrate was concentrated. Flash chromatography with CHCl 3 /MeOH/NH 3 solution (200:25: 1;) gave 3-(R5)- aminomethyl-l-(3,4-dichloro-benzyl)pyrrolidine compound as a colorless oil (6.2 g) which was >95 % pure. Example 4 Synthesis of N-[l -(2,3-dichlorobenzyl)pyrrolidin-3-(R5)-ylmethyl]-3-[5-(4- methoxyphenyl)pyrimidin-2-yl]propionamide hydrochloride salt Step 1 Methyl l-benzyl-5-oxo-3-pyrrolidinecarboxylate (50g, 0.21 mol) was stirred in a solution of ammonia in methanol (7 M, 400 mL, 2.8 mol). After 2 days, the solution was concentrated with heating (50 °C) to about 300 mL at which point all solids remained dissolved. The reaction was then allowed to cool down and the resulting solid was filtered, washed with ether and dried to give l-benzyl-5-oxo-pyιτolidine-3- carboxylic acid amide as colorless crystals (40 g). Step 2 l-Benzyl-5-oxo-pyrrolidιnc-3-carboxylic acid amide (22 g, 0.1 mol) was added portionwise to a stirred solution of lithium aluminum hydride (9.5 g, 0.25 mol, 2.5 equiv.) in dry tetrahydrofuran (600 mL). After the initial effervescence had subsided, the reaction mixture was heated at reflux at room temperature for 24 h, at which time analysis of the reaction mixture by LCMS showed there was no starting material. The reaction mixture was quenched by dropwise addition of saturated sodium sulphate solution with stirring until no further effervescence was observed. The suspension was filtered through a celite plug, eluting with diethyl ether (200 mL). The solvent was remove to afford 3-(RS)-aminomethyl-l-benzylpyrrolidine as an oil (14.7 g) which was used directly without further purification. Step 3 3-(R5)-Aminomethyl-l-benzylpyrrolidine (14.7 g, 80 mmol) was dissolved in methylene chloride (400 mL) with stirring. A solution of di-tert-butyl dicarbonate (16.8 g, 80 mmol, 1.0 equiv.) in methylene chloride (50 mL) was added dropwise and the reaction mixture was stirred overnight. The reaction mixture was concentrated and the residue was dissolved in diethyl ether (400 mL) and extracted with NaHSO solution (1 M, 120 mL). The aqueous layer was basified to pH 12 with 1 M sodium hydroxide and extracted with ethyl acetate. The organic fractions were combined, washed with brine, dried over magnesium sulfate, and filtered. The organics were evaporated to afford l-benzyl-3-( ?5)-(Λ f -terr-butoxycarbonylaminomethyl)pyrrolidine (22.5 g) which was used directly. Step 4 l-Bcnzyl-3-( ?S)-(/V-tert-butoxycarbonylaminomethyl)pyπOlidine (22.2 g, 0.76 mol) was dissolved in a mixture of methanol and acetic acid (1 : 1, 100 mL) and added to a Parr flask charged with palladium on carbon ( 10 %, 4 g) suspended in methanol and acetic acid ( 1 : 1, 100 mL). The flask was transferred to the Parr reduction apparatus and the suspension shaken under an atmosphere of hydrogen at 60 psi for 2 days. The reaction mixture was filtered through a celite plug, eluting with a mixture of methanol/methylene chloride. The solvent was concentrated and the residue co- evaporated with toluene to afford 3-(R5)-(N-tert-butoxycarbonylaminomethyl)- pyrrolidine as a colorless oil which was used directly. Step 5 Sodium triacetoxyborohydride (3.2 g, 15 mmol, 1.5 equiv.) was added in one portion to a stirred solution of 3-( ?5)-(N-tert-butoxycarbonylaminomethyl)pyrrolidine (2.0 g, 10 mmol) and 2,3-dichlorobenzaldehyde (1.9 g, 1 1 mmol, 1.1 equiv.) in dichloroethane (60 mL) at room temperature. The suspension was stirred overnight, then concentrated in vacuo. The residue was diluted with ether and quenched with 1 M hydrochloric acid. The aqueous phase was basified with 4 M sodium hydroxide to pH 12, then extracted with ethyl acetate. The organic extracts were combined and washed with brine, then dried over sodium sulfate and concentrated. Flash chromatography of the residue afforded 3-(R5)-(N-tert-butoxycarbonylaminomethyl)-l-(2,3- dichlorobenzyl)-pyrrolidine as a colorless oil (2.9 g). The oil was taken up into methylene chloride (30 L) and treated with neat trifluoroacetic acid (5 mL). After 1 h, the volatile components were removed on a vacuum pump, then concentrated further under high vacuum to give 3-(R5)-aminomethyl-l-(2,3-dichlorobenzyl)pyrrolidine which was used directly without further purification. Step 6 A solution of sodium ethoxide (21% wt vol in ethanol, 10 mL, 30 mmol, 3 equiv.) was added in one portion to a suspension of 2-(4-methoxyphenyl)trimethinium perchlorate (3.3 g, 9.8 mmol) [see, Jutz, C; Kirchlcchner, R.; Seidel, H. Chem. Ber. 102, 2301, ( 1969)] and 4-amidinobutanoic acid mono HCl ( 1.5 g, 9.8 mmol) [see, McElvain, S.M.; Schroeder, J.P. J. Am. Chem. Soc, 71 , 40, ( 1949)] in absolute ethanol (40 mL). The reaction mixture was heated at reflux for 12 h, then cooled to room temperature. The suspension was concentrated, diluted with water, and washed with ether. The aqueous phase was then made acidic with citric acid (10 g). The precipitates were filtered, washed with water and ether, and dried under high vacuum to yield 3-[4-(4-methoxyphenyl)-pyrimidin-2-yl]propanoic acid (1.85 g) as an off- white solid. Step 7 l-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.29 g, 1.5 mmol, 1.5 equiv.) was added to a suspension of 3-[4-(4-methoxyphenyl)pyrimidin-2- yl]-propanoic acid (0.26 g, 1.0 mmol, 1.0 equiv.), 3-(/?S)-aminomethyl-l-(2,3- dichlorobenzyl)-pyrrolidine (0.26 g, 1.0 mmol), 1-hydroxybenzotriazole hydrate (0.20 g, 1.5 mmol, 1.5 equiv.), and diisopropylethylamine (0.44 mL, 2.5 mmol, 2.5 equiv.) in chloroform (2 mL). After stirring overnight at room temperature, the reaction mixture was diluted with ethyl acetate, washed sequentially with 1 M sodium hydroxide, water, 1 M hydrochloric acid, water and brine, then dried over sodium sulfate and concentrated. The residue was purified by flash chromatography (0— >10% methanol in methylene chloride). Clean fractions containing the desired product were combined and concentrated, diluted with dioxane and treated with 4 M HCl (0.2 mL) in dioxane. The solution was concentrated under high vacuum to give N-(l-(2,3-dichlorobenzyl)- pyrrolidin-3-(R5)-ylmethyl)-3-(5-(4-methoxyphenyl)pyrimidin-2-yl)propionamide as the HCl salt (185 mg). Example 5 Synthesis of N-[ l-(2,3-dichlorobenzyl)pyrrolidin-3-(RS)-ylmethyl]-3- [5-(4-nitrophenyl)pyrimidin-2-yl]piOpionamide Step 1 Phosphorus oxychloride (83 mL, 0.79 mol) was added slowly to cold, dry dimethyl formamide (100 mL) under Ν 2 at such a rate that the temperature did not rise above 5 °C. After addition was complete, 4-nitrophenylacetic acid (48 g, 0.26 mol) was added in one portion and the reaction mixture was heated to 85 °C over 1 h. After 1 h, the reaction mixture was cooled, then poured over ice. Solid sodium perchlorate monohydrate (37 g, 0.26 mol) was added to initiate precipitation of the product as the perchlorate salt. Filtration of the solid, followed by washings with cold water, methanol and ether, gave 2-(4-nitrophenyl)trimethinium perchlorate (81.9 g) as a pale yellow solid. Step 2 A solution of sodium ethoxide (21% wt/vol, in ethanol, 60 mL, 180 mmol, 3 equiv.) was added in one portion to a suspension of 2-(4-nitrophenyl)trimethinium perchlorate (20.8 g, 60 mmol) and 4-amidinopropionic acid mono hydrochloride salt (9.1 g, 60 mmol) in ethanol (300 mL). The suspension was heated at room temperature overnight. The resulting suspension was filtered, washed with ethanol, cold HCl, water and ether, then dried under high vacuum to give 3-[5-(4-nitrophenyl)pyrimidin- 2-yl]-propanoic acid (13.7 g) as a beige solid. Step 3 l-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (5.8 g, 30 mmol, 1.5 equiv.) was added to a suspension of 3-[4-(4-nitrophenyl)pyrimidin-2- yl]propanoic acid (6.6 g, 24 mmol, 1.2 equiv.), (l-t^rt-butoxycarbonyl)-3-(RS)- aminomethylpyrrolidine (4.0 g, 20 mmol), 1-hydroxybenzotriazole hydrate (4.1 g, 30 mmol, 1.5 equiv.), and triethylamine (7.0 mL, 50 mmol, 2.5 equiv.) in chloroform (50 mL). Dimethylformamide (100 mL) was added to fully dissolve the reaction components and the solution was stirred at room temperature overnight. The reaction mixture was diluted with ethyl acetate, washed sequentially with 1 M sodium hydroxide, water, 1 M hydrochloric acid, water and brine, then dried sodium sulfate and concentrated to afford a light brown solid. This material was washed with ether to afford clean N-[ l-(2,3-dichlorobenzyl)pyrrolidin-3-(/?S)-ylmethyl]-3-[5-(4- nitrophenyl)pyrimidin-2-yl]propionamide (4.9 g). Example 6 Synthesis of N-[ l -(2,3-dichlorobenzyl)pyrrolidin-3-(/?5)-ylmethyl]-3-[5-(4- aminophenyl)pyrimidin-2-yl]propionamide Hydrogen gas (balloon pressure) was introduced into a vessel containing Pd / C (10 %, 100 mg, 0.1 mmol, 0.05 equiv.) in a solution of N-[ l-(2,3-dichlorobenzyl)- pyrrolidin-3-(R5)-ylmethyl]-3-[5-(4-nitrophenyl)pyrimidin-2-yl]propionamide (1.0 g, 2.2 mmol) in methanol (30 mL). After 1.5 h, the reaction was terminated by purging with N 2 and the reaction mixture was filtered through celite'' and concentrated. The yellow residue was dissolved in ethyl acetate, then taken into the aqueous phase using 1 M hydrochloric acid. The aqueous phase was basified to pH 1 1, then extracted thoroughly with ethyl acetate. The organic fractions were combined and washed with brine, then dried sodium sulfate and concentrated to afford N-[ l-(2,3- dichlorobcnzyl)pyrrolidιn-3-(/?5)-ylmethyl]-3-[5-(4-aminophenyl)pyrimidin-2- yl]propionamide as a yellow crystalline solid (630 mg). Example 7 Synthesis of N-(l-(2,3-dichlorobenzyl)pyrrolidin-3-(RS)-ylmethyl)-2-[5-(4- methoxyphenyl)-pyrimidin-2-ylsulfanyl]acetamide Step 1 Benzaldehyde (5.3 g, 50 mmol) was added to a solution of 3-(R5)- aminomethyl-pyrrolidine (5.0 g, 50 mmol) in toluene (anhydrous, 100 mL) in a 250 mL flask at room temperature under N 2 . A Dean-Stark apparatus and condenser were fitted, the reaction vessel well lagged and the reaction mixture heated at a strong reflux for 4 h. The reaction mixture was cooled to room temperature and di-tert-butyl dicarbonate (5.3 g, 50 mmol) was added portion-wise and the resulting solution was stirred at room temperature overnight. The reaction mixture was concentrated on the rotavap then the residue was diluted with 1 M NaHSO4 (80 mL, 80 mmol, 1.6 equiv.) and stirred vigorously for 2 h. The reaction mixture was washed with ether to remove unwanted organic byproducts, then basified with 1 M NaOH to pH 7. Further extraction with ethyl acetate removed additional unwanted byproducts. The aqueous solution was then made strongly basic (pH 12) with 1 M NaOH and extracted thoroughly with ethyl acetate. The organic layer was washed with brine, dried with sodium sulfate, then concentrated to give 3-(RS)-aminomethyl-l-tert- butoxycarbonylpyrrolidine as a colorless oil which was used directly without further purification. Step 2 3-(/?5)-aminomethyl-l-tert-butoxycarbonylpyrrolidine (6.0 g, 30 mmol) in methylene chloride (15 mL) was added dropwise to a cold (0 °C) solution of chloroacetylchloride (2.4 mL, 30 mmol) and diisopropylethylamine (5.5 mL, 32 mmol) in methylene chloride under N 2 . After 1 h, an additional 0.5 equiv. of chloroacetyl chloride and diisopropylamine were added. After being left at 0 °C overnight, the reaction mixture was diluted with ethyl acetate and washed briefly with water and brine, then dried over sodium sulfate and concentrated to give N-(l-tert- butoxycarbonylpyrrolidin-3-(R5)-ylmethyl)-2-chloroacetamide as a dark brown oil which was used without further purification. Step 3 A solution of sodium ethoxide (21 % wt/vol, 15 mL, 45 mmol, 1.5 equiv.) was added to a suspension of 2-(4-mcthoxyphenyl)trimethinium perchlorate ( 10.0 g, 30 mmol) and thiourca (3.0 g, 40 mmol, 1.3 equiv.) in ethanol (200 mL) (.see, Krecmerova, M.; Hrebabecky, H.; Masojidkova, M.; Holy, A. Collect. Czech. Chem. Commun., 61, 458, ( 1996)]. The reaction mixture was heated at 60 °C for 2 h. Additional quantities of thiourea and sodium ethoxide were added to the starting amounts and the reaction mixture was heated at 60 °C for an additional 1 h. The yellow suspension was cooled to room temperature, quenched with acetic acid ( 10 mL) and filtered. The solid was washed with water and ethanol and dried under high vacuum to give 5-(4-methoxyphenyl)-lH-pyrimidine-2-thione as a free flowing yellow powder (6.0 g). Step 4 5-(4-Methoxyphenyl)-lH-pyrimidine-2-thione (0.70 g, 3 mmol) was added to a solution of the N-(l-tert-butoxycarbonylpyrrolidin-3-(R5)-ylmethyl)-2- chloroacetamide (1.15 g, -80 % purity, ~3 mmol) and diisopropylethylamine (0.9 mL, 5 mmol, 1.5 equiv.) in dry acetonitrile. An ethanolic solution of sodium ethoxide (2.7 M, 1.2 mL, 3.2 mmol) and dimethylformamide (20 mL) were added in order to dissolve the starting mercaptan. The resulting dark brown solution was stirred at room temperature for 2 h. The reaction mixture was concentrated and the residue was chromatographed on silica gel (50-100% ethyl acetate in hexane). Fractions containing the major product were combined and concentrated to an oily residue. Trituration of the oil with ether afforded pure N-(l-tert-butoxycarbonylpyrrolidin-3-(RS)-ylmethyl)- 2-[5-(4-methoxyphenyl)pyrimidin-2-ylthio]-acetamide (0.60 g, 44 %) as a pale yellow solid. Step 5 Neat anhydrous trifluoroacetic acid (3 mL) was added to a solution of N-(l- tert-butoxycarbonylpyrrolidin-3-(RS)-ylmethyl)-2-[5-(4-methoxyphenyl)pyrimidin-2- ylthio]-acetamide (0.60 g, 1.3 mmol) in methylene chloride (20 mL) at room temperature. Gas evolution was apparent immediately upon addition of the acid. After 30 min., the reaction mixture was concentrated using a Teflon dryvac system, and was then further concentrated under high vacuum to give /V-(pyrrolidin-3-(/?S)-ylmethyl)-2- [5-(4-methoxyphenyl)pyrimidin-2-ylthio]acetamide which was dissolved in 10 mL dichloroethane (0.13 mmol/mL). Step 6 2,3-Dichlorobenzaldehyde ( 1 15 mg, 0.66 mmol, 1.5 equiv.) was added to N- (pyrrolidin-3-(Λ5)-ylmethyl)-2-[5-(4-methoxyphenyl)pyrimidin-2-ylthio]acctamide in dichloroethane (3.4 mL, 0.44 mmol). Excess Νa(OAc) 3 BH (0.2 g, 0.9 mmol, ~3 equiv.) was added and the resulting suspension was stirred vigorously overnight. The reaction mixture was diluted with ether and quenched with 1 M hydrochloric acid to afford a cloudy mixture. The organic layer was carefully removed and the aqueous phase made basic with 5 M aqueous sodium hydroxide to pH 11. After thorough extraction with ethyl acetate, the combined organic phases was washed with brine, then dried over sodium sulfate and concentrated. Chromatography on silica (0-10% methanol in ethyl acetate) afforded N-(l-(2,3-dichlorobenzyl)pyrrolidin-3-(RS)- ylmethyl)-2-[5-(4-methoxyphenyl)-pyrimidin-2-ylsulfanyl]acetamide that was converted to the hydrochloride salt using 4 M hydrochloric acid solution in dioxane and ether (60 mg). Proceeding as described in Step 6 above, but substituting 2,3-dichloro- benzylaldehyde (1 15 mg, 0.66 mmol, 1.5 equiv.) with 3,4-dichlorobenzaldehyde gave N-(l-(3,4-dichlorobenzyl)pyrrolidin-3-(RS)-ylmethyl)-2-[5-(4-methoxyphenyl)- pyrimidin-2-ylsulfanyl]acetamide hydrochloride salt. Proceeding as described in Step 6 above, but substituting 2,3-dichloro- benzylaldehyde with 3,4-methylenedioxybenzaldehyde gave N-(l-(3,4-methylene- dioxybenzyl)pyrrolidin-3-(RS)-ylmethyl)-2-[5-(4-methoxyphenyl)pyrimidin-2- ylsulfanyl]-acetamide hydrochloride salt. Example 8 Synthesis of N-[ 1 -(3,4-dichlorobenzyl)pyrrolidin-3-(/v\S)-ylmethyl]- 2-[5-(4-methoxyphcnyl)pyrimidin-2-yloxy]acctamide Step 1 The procedure for the synthesis of 5-bromo-2-hydroxypyrimidine used is a variation of that published by Crosby and Berthold, J. Chem. Soc. 25, 1916, (1960). To a solution of 2-hydroxypyrimidine hydrochloride (100 g, 0.75 mol) in water (1.2 L) was added bromine (135 g, 0.84 mol) slowly with stirring. The reaction mixture was continuously stirred for about 30 min., until the red color of the solution became lighter. The solution was heated to 80 °C to drive of excess Br 2 and HBr. The solvent was concentrated further under vacuum and the residue recrystallized from 90% aqueous ethanol to afford 5-bromo-2-hydroxypyrimidine (11 1 g). Step 2 Phosphorus oxychloride (225 mL, 2.4 mol, 1.4 equiv.) was added to a mixture of 5-bromo-2-hydroxypyrimidine (30 g, 0.17 mol) and dimethylaniline (7.5 mL) and the solution was heated at reflux under N 2 for 4 h. The dark brown reaction mixture was cooled, poured over ice and extracted with ether. The organic phase was washed with bicarbonate solution, dried sodium sulfate and concentrated to afford 5-bromo-3- chloropyrimidine (25 g, 75 %) [see, Goodby, J.W.; Hird, M.; Lewis, R.A.; Toyne, K.J. J. Chem. Soc, Chem. Commun., 2719, (1996)]. Step 3 The synthesis of (5-bromopyrimidin-2-ylo.\y)acetic acid followed the protocol described for similar analogues by Coppola, G.M.; Hardtmann, G.E.; Huegi, B.S. J. Heterocyl. Chem., 17, 1479, ( 1980). Sodium hydride (5.0 g, 60 % dispersion in mineral oil, 124 mmol, 1.8 equiv.) was washed twice with dry hexane under N 2 , then added portionwise to a solution of methyl glycolatc (9.4 g, 103 mmol, 1.5 equiv.) in toluene (150 mL). The reaction mixture was stirred at room temperature for 30 min., then 5-bromo-3-chloropyrimidine (13.3 g, 69 mmol) in toluene (50 mL) was added. The reaction mixture was heated at 60 °C overnight and concentrated. The residue was stirred rapidly with 1 M aqueous sodium hydroxide (excess) for 30 min., washed with ether, then acidified to with 4 M hydrochloric acid. The resulting precipitate was collected and washed with cold water. The filtrate was extracted further with ethyl acetate, and the organic phase washed with brine, then dried sodium sulfate and concentrated to give (5-bromopyrimidin-2-yloxy)acetic acid (10.3 g). Step 4 To a solution of 3-(RS)-aminomethyl-l-tert-butoxycarbonylpyrrolidine in dichloroethane (17 mL) were sequentially added diisopropylethylamine (5.1 mL), a solution of 2-(5-bromopyrimidin-2-yloxy)acetic acid (2.9 g, 12.2 mmol, 1.1 equiv.) in tetrahydrofuran (43 L), 1-hydroxybenzotriazole hydrate (2.4 g, 17.5 mmol, 1.5 equiv.) and l-(3-dimethyl-aminopropyl)-3-ethylcarbodiimide hydrochloride (3.4 g, 17.6 mmol, 1.5 equiv.). The solution was stirred under N 2 overnight. The reaction mixture was diluted with ethyl acetate, washed with 1 M aqueous sodium hydroxide, 1 M hydrochloric acid, water and brine, then dried over sodium sulfate and concentrated. The residue was subjected to flash chromatography to afford clean N-(\-tert- butoxycarbonylpyrrolidin-3-(R5)-ylmethyl)-2-(5-bromopyrimidin-2-yloxy)acetamide (4.2 g). Step 5 4-Methoxyphenylboronic acid (1.0 g, 6.8 mmol, 1.05 equiv.) was added to a solution of N-(l-tert-butoxycarbonylpyιτolidin-3-(RS)-ylmethyl)-2-(5-bromopyrimidin- 2-yloxy)acetamide (2.7 g, 6.5 mmol) in 1-propanol (30 mL). The suspension was stirred until all ingredients had dissolved (- 10 min). The resulting solution was treated with palladium acetate (29 mg, 0.13 mmol, 0.02 equiv.), triphenylphosphine (103 mg, 0.39 mmol, 0.06 equiv.), 2 M aqueous sodium carbonate (3.9 mL, 7.8 mmol, 1.2 equiv.) and deionized water (9 L). The reaction mixture was heated at reflux under Ν 2 for 1 h. Water (20 mL) was added and the N 2 inlet was removed. After stirring at room temperature overnight, the reaction mixture was thoroughly extracted with ethyl acetate. The combined organic phase was washed with saturated sodium bicarbonate solution and brine. The organic phase was stirred with activated charcoal for 15 min, dried over sodium sulfate and concentrated. Recrystallization of the residue from ethyl acetate in hexane afforded clean N-(l-tert-butoxycarbonylpyrrolidin-3-(R4S)-ylmethyl)- 2-(5-(4-methoxyphenyl)pyrimidin-2-yloxy)acetamide (2.1 g). The solid was dissolved into methylene chloride (30 mL) and neat trifluoroacetic acid (5 mL) added dropwise. After about 1 h, the solution was concentrated to an oil on a Teflon dryvac, then under high vacuum to give N-(pyrrolidin-3-(RS)-ylmethyl)-2-[5-(4- methoxyphenyl)pyrimidin-2-yloxy]acetamide. Step 6 A stock solution containing N-(pyrrolidin-3-(RS)-ylmethyl)-2-(5-(4-methoxy- phenyl)pyrimidin-2-yloxy)acetamide (0.44 mmol) in dichloroethane (10 mL) was added to a solution of 3,4-dichlorobenzaldehyde (85 mg, 0.48 mmol, 1.1 equiv.) and diisopropylethylamine (0.35 mL, 2.0 mmol, 4.5 equiv.) in dichloroethane (5 mL). Excess Na(OAc) 3 BH (140 mg, 0.66 mmol, 1.5 equiv.) was added and the reaction mixture was stirred rapidly at room temperature overnight. The reaction mixture was quenched with methanol, concentrated and diluted with 1: 1 methanol/dimethyl sulfoxide. The solution was then purified directly using preparative reverse phase chromatography to give, after treatment with 4 M hydrochloric acid in dioxane (1 mL) and concentration, N-[l-(3,4-dichlorobenzyl)pyrrolidin-3-(RS)-ylmethyl]-2-[5-(4- methoxyphenyl)pyrimidin-2-yloxy]-acetamide HCl salt (96 mg). Example 9 Synthesis of N-[ 1 -(2,3-dichlorobenzyl)pyrrolidin-3-(/?S)-ylmethyl]-2-[5-(4-methoxy- pheny!)pyrimidin-2-ylamino]acetamide hydrochloride salt Step 1 An ethanolic solution of sodium ethoxide (2.7 M, 3.8 mL, 10 mmol, 2.9 equiv.) was added to a suspension of 2-(4-methoxyphenyl)trimethinium perchlorate salt (1.1 g, 3.4 mmol) and guanidineacetic acid (0.48 g, 4.0 mmol, 1.2 equiv.) in dehydrated ethanol (20 mL). The reaction mixture was stirred at room temperature for 30 min., then at reflux temperature for 3 h. After cooling, the sodium salt was filtered, and the cake dissolved in 20 mL of water then acidified with 1 M hydrochloric acid. The aqueous layer was extracted with ethyl acetate and the combined organic phases was washed with brine, and dried over sodium sulfate. Removal of the solvent under vacuum afforded a solid which contained -1: 1 mixture of regioisomers. The two components were separated using reversed-phase chromatography to give 2-[5-(4- methoxyphenyl)pyrimidin-2-ylamino]-acetic acid (150 mg) and the regioisomer (100 mg). Step 2 Solid l-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (14 mg, 0.08 mmol, 1.5 equiv.) was added to a solution of 3-(RS)-aminomethyl-l-(2,3- dichlorobenzyl)-pyrrolidine (13 mg, 0.05 mmol), 2-[5-(3-methoxyphenyl)pyrimidin-2- ylaminojacetic acid (16 mg, 0.06 mmol, 1.2 equiv.), 1-hydroxybenzotriazole hydrate (10 mg, 0.08 mmol, 1.5 equiv.) and diisopropylethylamine (22 mL, 0.13 mmol, 2.5 equiv.) in dimethyl formamide (0.5 mL). The reaction mixture was shaken at room temperature overnight. The reaction mixture was quenched with methanol (0.3 mL), then purified directly by reverse phase preparative HPLC to give N-[ l -(2,3- dichlorobenzyl)pyπOlidin-3-(/?S)-ylmcthyl]-2-[5-(4-methoxyphenyl)pyrimidin-2- ylamino]acetamide HCl salt ( 1 1 mg). Example 10 Synthesis of N-[ l-(3,4-dichlorobenzyl)pyιτolidin-3-(R5)-ylmethyl]-4-(2,5- dimethylphenyl)-4-oxo-butyramide trill uoroacctatc salt To a solution (1 mL) of l-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (55 mg, 0.28 mmol, 1.8 equiv.), 1-hydroxybenzotriazole hydrate (38 mg, 0.28 mmol, 1.8 equiv.) and triethylamine (43 mL, 0.31 mmol, 2.0 equiv.) in chloroform were added solid 4-(2,5-dimethylphenyl)-4-oxobutyric acid (39 mg, 0.19 mmol, 1.2 equiv.) and 3-(R5)-aminomethyl-l-(3,4-dichlorobenzyl)pyrrolidine (40 mg, 0.16 mmol) in chloroform (1 mL). The reaction mixture was shaken overnight, then concentrated and diluted with dimethylsulfoxide/methanol (1: 1, 1 mL). The reaction mixture was purified by reversed phase chromatography to give N-[ l-(3,4- dichlorobenzyl)pyrrolidin-3-(RS)-ylmethyl]-4-(2,5-dimethylphenyl)-4-oxo-butyramide trifluoroacetate salt as a colorless oil (33 mg). Other examples: Proceeding as described above but substituting 4-(2,5-dimethylphenyl)-4-oxo- butyric acid with (4-acetylphenoxy)acetic acid gave 2-(4-acetylphenoxy)- V-[ l-(3,4- dichlorobenzyl)pyrrolidin-3-(/?S)-ylmethyl]acetamide.

Exp. Med., Vol. 183, 2437-2448, (1996)). The assay was performed in Costar 96-well polypropylene round bottom plates. Test compounds were dissolved in DMSO and then diluted with binding buffer (50 mM HEPES, 1 mM CaCl 2 , 5 mM MgCl 2 , 0.5% bovine serum albumin (BSA), 0.02% sodium azide, pH 7.24) such that the final DMSO concentration was 2%. 25μl of the test solution or only buffer with DMSO (control samples) was added to each well, followed by the addition of 25μl of 125 I-eotaxin (100 pmol) (NEX314, New England Nuclear, Boston, MA) and 1.5 x 10 5 of the CCR-3 LI.2 transfected cells in 25μl binding buffer. The final reaction volume was 75μl. After incubating the reaction mixture for lh at room temperature, the reaction was terminated by filtering the reaction mixture through polyethylenimine treated Packard Unifilter GF/C filter plate (Packard, Chicago, II.). The filters were washed four times with ice cold wash buffer containing 10 mm HEPES and 0.5M sodium chloride (pH 7.2) and dried at 65 °C for approximately 10 min. 25 μl/well of Microscint-20™ scintillation fluid (Packard) was added and the radioactivity retained on the filters was determined by using the Packard TopCount™. The IC 5 o value (concentration of test compound required to reduce 12D I-eotaxin binding to the CCR-3 L 1.2 transfected cells by 50%) for compounds in Tables I-V of the invention was between 0.02 and 200μM. Example 15 Inhibition of Eotaxin mediated chemotaxis of CCR-3 LI .2 transfectant cells— //; vitro Assay The CCR-3 antagonistic activity of the compounds of this invention was determined by measuring the inhibition of eotaxin mediated chemotaxis of the CCR-3 LI .2 transfectant cells, using a slight modification of the method described in Ponath, P. D. et al., J. Clin. Invest. 97: 604-612 (1996). The assay was performed in a 24-well chemotaxis plate (Costar Corp., Cambridge MA). CCR-3 LI.2 transfectant cells were grown in culture medium containing RPMI 1640, 10% Hyclone™ fetal calf serum, 55 mM 2-mercaptoethanol and Geneticin 418 (0.8 mg/ml). 18-24 hours before the assay, the transfected cells were treated with n-butyric acid at a final concentration of 5 mM 1 x 10 6 cells/ml, isolated and resuspended at 1 x 10 cells/ml in assay medium containing equal parts of RPMI 1640 and Medium 199 (M 199) with 0.5% bovine serum albumin. Human eotaxin suspended in phosphate buffered saline at 1 mg/ml was added to bottom chamber in a final concentration of 100 nm. Transwell culture inserts (Costar Corp., Cambridge MA) having 3 micron pore size were inserted into each well and LI.2 cells (1 x 10 6 ) were added to the top chamber in a final volume of lOOμl. Test compounds in DMSO were added both to the top and bottom chambers such that the final DMSO volume was 0.5%. The assay was performed against two sets of controls. The positive control contained cells with no test compound in the top chamber and only eotaxin in the lower chamber. The negative control contained cells with no test compound in the top chamber and neither eotaxin nor test compound in lower chamber. The plate was incubated at 37 °C. After 4 h, the inserts were removed from the chambers and the cells that had migrated to the bottom chamber were counted by pipetting out 500 μl of the cell suspension from the lower chamber to 1.2 ml Cluster tubes (Costar) and counting them on a FACS for 30 sec. The IC 5 o value (concentration of test compound required to reduce eotaxin mediated chemotaxis of CCR-3 L 1.2 transfected cells by 50%) for representative compounds of the invention was between 0.006 to 1.1 μm. Example 16 Inhibition of Eotaxin mediated chemotaxis of human eosinophils— In vitro Assay The ability of compounds of the invention to inhibit eotaxin mediated chemotaxis of human eosinophils was assessed using a slight modification of procedure described in Carr, M.W. et al., Proc. Natl. Acad. Sci. USA, 91: 3652-3656 (1994). Experiments were performed using 24 well chemotaxis plates (Costar Corp., Cambridge MA). Eosinophils were isolated from blood using the procedure described in PCT Application, Publication No. WO 96/22371. The endothelial cells used were the endothelial cell line ECV 304 obtained from European Collection of Animal Cell Cultures (Porton Down, Salisbury, U.K.). Endothelial cells were cultured on 6.5 mm diameter Biocoat® Transwell tissue culture inserts (Costar Corp., Cambridge MA) with a 3.0 μM pore size. Culture media for ECV 304 cells consisted of M199, 10% Fetal Calf Serum, L-glutamine and antibiotics. Assay media consisted of equal parts RPMI 1640 and M199, with 0.5% BSA. 24 h before the assay 2 x 10 5 ECV 304 cells were plated on each insert of the 24-well chemotaxis plate and incubated at 37 °C. 20 nM of eotaxin diluted in assay medium was added to the bottom chamber. The final volume in bottom chamber was 600 μl. The endothelial coated tissue culture inserts were inserted into each well. 10 6 eosinophil cells suspended in 100 μl assay buffer were added to the top chamber. Test compounds dissolved in DMSO were added to both top and bottom chambers such that the final DMSO volume in each well was 0.5%. The assay was performed against two sets of controls. The positive control contained cells in the top chamber and eotaxin in the lower chamber. The negative control contained cells in the top chamber and only assay buffer in the lower chamber. The plates were incubated at 37 °C in 5% CO 2 /95% air for 1-1.5 h. The cells that had migrated to the bottom chamber were counted using flow cytometry. 500 μl of the cell suspension from the lower chamber was placed in a tube, and relative cell counts were obtained by acquiring events for a set time period of 30 seconds. Example 17 Inhibition of Eosinophil influx into the lungs of Ovalbumin sensitized balb/c mice by CCR-3 Antagonist —In vivo Assay The ability of the compounds of the invention to inhibit leukocyte infiltration into the lungs was determined by measuring the inhibition of eosinophil accumulation into the bronchioalveolar lavage (BAL) fluid of Ovalbumin (OA)-sensitized balb/c mice after antigen challenge by aerosol. Briefly, male balb/c mice weighing 20-25g were sensitized with OA (10 μg in 0.2 ml aluminum hydroxide solution) intraperitoneally on days 1 and 14. After a week, the mice were divided into ten groups. Test compound or only vehicle (control group) or anti-eotaxin antibody (positive control group) was administered either intraperitoneally, subcutaneously or orally. After 1 h, the mice were placed in a Plexiglass box and exposed to OA aerosol generated by a PARISTAR™ nebulizer (PARI, Richmond, VA) for 20 min. Mice which had not been sensitized or challenged were included as negative control. After 24 or 72 h, the mice were anesthetized (urethane, approx. lg/kg, i.p.), a tracheal cannula (PE 60 tubing) was inserted and the lungs were lavaged four times with 0.3 ml PBS. The BAL fluid was transferred into plastic tubes and kept on ice. Total leukocytes in a 20 μl aliquot of the BAL fluid was determined by Coulter Counter™ (Coulter, Miami, FI). Differential leukocyte counts were made on Cytospin™ preparations which had been stained with a modified Wright's stain (Diff-Quick™) by light microscopy using standard morphological criteria. The ID 5 o for the compounds of this invention in this assay is between 30 and 50 mgs/kg.
