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 (120 mg, 0.21 mmol) in methylene chloride (10 mL), HATU (Aldrich, 157 mg, 0.41 mmol) was added followed by the addition of DIPEA (110 uL, 0.62 mmol) and 2-amino benzoic acid t-butyl ester (Aldrich, 80 mg, 0.41 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, eluent, 20% EtOAc/hexanes) to give a white solid. 71 mg.
