Procedure

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 (80 mg, 0.138 mmol) in methylene chloride (5 mL), HATU (Aldrich, 79 mg, 0.21 mmol) was added followed by the addition of DIPEA (0.145 mL, 0.83 mmol) and 2-piperazin-1-yl-acetamide (Chembridge, 45 mg, 0.21 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 a ISCO machine (12 g column, eluent, 20% EtOAc/methylene chloride) to give a white solid. 87 mg.
