Reaction Steps

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 (80 mg, 0.14 mmol) in methylene chloride (10 mL), HATU (Aldrich, 105 mg, 0.28 mmol) was added followed by the addition of DIPEA (0.34 mmol) and 2-hydroxy-2-methyl-propylamine (Matrix, 25 mg, 028 mmol). The mixture was stirred at rt 1 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 (40 g column, eluent, 35-50% EtOAc/hexanes) to give a white solid. 50 mg.
