Procedure

A mixture of rac-(3-{[(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-carbonyl]-amino}-pyrazol-1-yl)-acetic acid (85 mg, 0.144 mmol), ammonia (0.57 mL, 0.288 mmol, 0.5 M in dioxane), 2-(7-azabenzotriazol-1-yl)-n,n,n′,n′-tetramethyluronium hexafluorophosphate (HATU, 109 mg, 0.288 mmol) and iPr2NEt (0.1 mL, 0.43 mmol) in CH2Cl2 (10 mL) was stirred at rt overnight. The mixture was then diluted with CH2Cl2 and washed with water, brine. The organic phase was separated, dried over Na2SO4 and filtered. The mixture was then concentrated and purified by reverse phase chromatography (20-95% of ACN/water) rac-(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 (2-[1,2,3]triazol-1-yl-ethyl)-amide (12.3 mg, 14.5%) as an off-white powder. HRMS (ES+) m/z Calcd for C28H28Cl2F2N6O2+H [(M+H)+]: 589.1692. found: 589.1693.
