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 (250 mg, 0.44 mmol) in methylene chloride (10 mL), HATU (Aldrich, 332 mg, 0.88 mmol) was added followed by the addition of DIPEA (0.230 mL, 1.31 mmol) and 3-amino-phenyl methyl sulfide (Aldrich, 122 mg, 0.88 mmol). The mixture was stirred at rt for 2 hr. 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 (50 g column, eluent EtOAc/Hexanes, 5-10%) to give a white solid. 178 mg.
