実験手順

A mixture rac-(2R,3S,4R,5S)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-3-fluoro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carboxylic acid (125 mg, 0.267 mmol), 2-((S)-2,2-dimethyl-[1,3]dioxolan-4-yl)-ethylamine (0.2 mg, 1.3 mmol), 2-(7-azabenzotriazol-1-yl)-n,n,n′,n′-tetramethyluronium hexafluorophosphate (HATU, 114.1 mg, 0.3 mmol) and iPr2NEt (0.3 mL, 3.22 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 reverse phase chromatography (20-95% of ACN/water) to give rac-(2R,3S,4R,5S)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-3-fluoro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carboxylic acid [2-((S)-2,2-dimethyl-[1,3]dioxolan-4-yl)-ethyl]-amide (101 mg, 63.5%) as an off-white powder. HRMS (ES+) m/z Calcd for C30H35Cl2N3O3S+H [(M+H)+]: 594.2097. found: 594.2096.
