To a stirred solution of rac (2R,3S,4R,5S)-3-(3-Chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carboxylic acid (150 mg, 0.26 mmol) in methylene chloride (10 mL), HATU (Aldrich, 177 mg, 0.46 mmol) was added followed by the addition of DIPEA (0.36 mL, 2.06 mmol) and 3-aminomethyl-benzoic acid methyl ester hydrochloride salt (Aldrich, 104 mg, 0.52 mmol). The mixture was stirred at rt for overnight. The reaction was quenched with addition of water. The mixture was extracted with methylene chloride (2×10 mL) and the extracts were dried with magnesium sulfate. The solvent was removed and the residue was purified on an ISCO machine (40 g column, 5-15% EtOAc/hexanes) to give a white solid. 118 mg.
