Participants

Reaction Steps

To a stirred solution rac 3-{[(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-carbonyl]-amino}-benzoic acid (80 mg, 0.14 mmol) in methylene chloride (10 mL), HATU (Aldrich, 104 mg, 0.27 mmol) was added followed by the addition of DIPEA (0.41 mmol) and 2-hydroxy-2-methyl-propylamine (Matrix, 24 mg, 027 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. 75 mg.
