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 (100 mg, 0.172 mmol) in methylene chloride (10 mL), HATU (Aldrich, 130 mg, 0.344 mmol) was added followed by the addition of DIPEA (90 uL, 0.52 mmol) and 3-(1H-tetrazol-5-yl)-phenylamine (Alfa, 55 mg, 0.344 mmol). The mixture was stirred at rt for 2 hrs. 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 reverse phase HPLC (24 g column, eluent, 30% EtOAc/methylene chloride) to give a yellow solid. 21 mg.
