Procedure

A solution of chiral (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 (59.9 mg, 0.128 mmol) in dichloromethane (3 ml) was treated with DIPEA (66.8 mg, 0.514 mmol) and DIPHENYLPHOSPHINIC CHLORIDE (75.8 mg, 0.314 mmol) and stirred for 20 min under argon. 2-MORPHOLIN-4-YLPYRIMIDIN-5-AMINE (23.4 mg, 0.130 mmol, Atlantic Research) was added. After stirred 2.5 hrs, the reaction mixture was diluted with dichloromethane, washed with sat. NaHCO3, water and brine. After dried over Na2SO4, the crude material was purified by silica gel chromatography with ethyl acetate and n-hexanes to give chiral (2R,3S,4R,5S)-3-(3-chloro-2-fluorophenyl)-4-(4-chloro-2-fluorophenyl)-4-cyano-N-(2-morpholinopyrimidin-5-yl)-5-neopentylpyrrolidine-2-carboxamide (78.4 mg., 97.2%) as a white solid. MS (ES+) m/z Calcd: [(M+H)+]: 629.19. found: 629.2.
