실험 절차

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, 0.17 mmol) in methylene chloride (10 mL), HATU (Aldrich, 98 mg, 0.26 mmol) was added followed by the addition of DIPEA (0.150 mL, 0.855 mmol) and 5-amino-2-fluoro-benzoic acid ethyl ester (Oakwood, 63 mg, 0.34 mmol). The mixture was stirred at rt for 1.5 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 an ISCO machine (50 g column, eluent EtOAc/Hexanes, 5-20%) to give a white solid. 64 mg.
