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 (86.2 mg, 0.20 mmol), 2-aminomethyl-propane-1,3-diol (31.5 mg, 0.3 mmol), 2-(7-azabenzotriazol-1-yl)-n,n,n′,n′-tetramethyluronium hexafluorophosphate (HATU, 76 mg, 0.2 mmol) and iPr2NEt (0.1 mL, 0.55 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,3R,4R,5S)-3-(3-chloro-phenyl)-4-(4-chloro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carboxylic acid (3-hydroxy-2-hydroxymethyl-propyl)-amide (31.2 mg, 30.9%) as an off-white powder. HRMS (ES+) m/z Calcd for C26H31Cl2N3O3S+H [(M+H)+]: 504.455. found: 504.1815. washed with water, brine The organic phase was separated filtered dried over Na2SO4 The mixture was then concentrated purified by reverse phase chromatography (20-95% of ACN/water)
