Versuchsvorschrift

Reagent 2-(4-amino-phenyl)-N-methyl-isobutyramide (130 mg, 0.676 mmol) was dissolved in dichloromethane (4 mL) then iPr2NEt (0.375 mL, 2.15 mmol) was added and stirred at 25° C. In three portions 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 (100 mg, 0.214 mmol) and 2-(7-azabenzotriazol-1-yl)-n,n,n′,n′-tetramethyluronium hexafluorophosphate (HATU, 106 mg, 0.278 mmol) was added in 30 min intervals. The reaction mixture was stirred at 25° C. for 5 hours, complete by LCMS. The mixture was then diluted with CH2Cl2 and washed with water. The organic phase was separated, then concentrated under reduced pressure. The compound was purified by RP-HPLC (30-95% acetonitrile/water) to afford chiral (2S,3R,4S,5R)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carboxylic acid [4-(1-methyl-1-methylcarbamoyl-ethyl)-phenyl]-amide as an off-white solid (56 mg, 40.8%) HRMS (ES+) m/z Calcd for C34H36Cl2F2N4O2+H [(M+H)+]: 641.2256. found: 641.2256.
