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, 0.22 mmol) in methylene chloride (10 mL), HATU (Aldrich, 83 mg, 0.22 mmol) was added followed by the addition of DIPEA (0.20 mL) and 1H-tetrazol-5-yl-methylamine hydrobromide (Aldrich, 54 mg, 0.3 mmol). The mixture was stirred at rt 4.5 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 a reverse phase HPLC to give a white solid. 47 mg.
