実験手順

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 (3-amino-propyl)-amide (120 mg, 0.24 mmol), methane sulfonyl chloride (49 μL, 0.6 mmol) and dimethylaminopyridine (97.6 mg, 0.8 mmol) in CH2Cl2 (8 mL) was stirred for 5 h at rt. The mixture was then extracted with NaHCO3(s), water and the organic layer dried with MgSO4, filtered and the solvent was evaporated under reduced pressure. diluted with CH2Cl2 and washed with water, brine. The organic phase was separated, filtered and dried over Na2SO4. The mixture was then purified by reverse phase chromatography (20-95% of ACN/water) 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 (3-methanesulfonylamino-propyl)-amide (112.1 mg, 80.5%) as an off-white powder. HRMS (ES+) m/z Calcd for C27H34Cl2N4O3S+H [(M+H)+]: 565.1802. found: 565.1800.
