Procedure

A mixture of rac-(2R,3R,4R,5S)-3-(3-chloro-phenyl)-4-(4-chloro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carboxylic acid (61.0 mg, 0.14 mmol), 2-morpholin-4-yl-ethylamine (36.0 mg, 0.28 mmol), 2-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (HATU, 106.0 mg, 0.28 mmol) and iPr2NEt (38.8 mg, 0.30 mmol) in CH2Cl2 (2 mL) was stirred at rt overnight. The mixture was then diluted with CH2Cl2 and washed with water, brine. The organic phase was separated, filtered and dried over Na2SO4. The mixture was then concentrated and purified by SiO2 flash column (20-100% of EtOAc in Hexanes) to give rac-(2R,3R,4R,5S)-3-(3-chloro-phenyl)-4-(4-chloro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carboxylic acid (2-morpholin-4-yl-ethyl)-amide (60.5 mg, 86.4%) as a white amorphous.
