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 (200 mg, 0.34 mmol) in methylene chloride (10 mL), HATU (Aldrich, 235 mg, 0.62 mmol) was added followed by the addition of DIPEA (0.30 mL, 1.72 mmol) and 4-amino-2-methyl-benzoic acid (Aldrich, 114 mg, 0.69 mmol). The mixture was stirred at rt 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/methylene chloride) to give a white solid. 102 mg.
