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 (150 mg, 0.26 mmol) in methylene chloride (10 mL), HATU (Aldrich, 147 mg, 0.39 mmol) was added followed by the addition of DIPEA (0.225 mL, 1.29 mmol) and 4-amino-ethyl-benzamide (made by reducing the corresponding nitro precursor, 56 mg, 0.34 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, 0-15% EtOAc/hexanes) to give a white solid. 42 mg.
