Reaction Steps

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), 4-aminomethyl tetrahydropyran (34.5 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 (tetrahydro-pyran-4-ylmethyl)-amide (10.8 mg, 10.2%) as an off-white powder. HRMS (ES+) m/z Calcd for C29H35Cl2N3O2S+H [(M+H)+]: 528.2179. found: 528.2180.
