Procedure
A mixture 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 (200 mg, 0.43 mmol), 3-aminothiophene-2-carboxylic acid amide (160 mg, 1.1 mmol), 2-(7-azabenzotriazol-1-yl)-n,n,n′,n′-tetramethyluronium hexafluorophosphate (HATU, 243.3 mg, 0.64 mmol) and iPr2NEt (0.3 mL, 1.67 mmol) in CH2Cl2 (5 mL) was stirred at rt overnight. The mixture was then diluted with CH2Cl2 and washed with water, brine. The organic phase was separated, dried over Na2SO4 and filtered. The mixture was then concentrated and purified flash column chromatography (1-100% ethyl acetate/heptane) to afford 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 (2-carbamoyl-thiophen-3-yl)-amide as a off white powder (15.8 mg, 6.2%). HRMS (ES+) m/z Calcd for C28H26Cl2F2N4O2S+H [(M+H)+]: 501.1195. found: 591.1191.
