A mixture of rac-(2R,3S,4R,5S)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-5-(2,2-dimethylpropyl)-pyrrolidine-2-carboxylic acid {1-[2-methyl-2-((S)-1-oxiranylmethoxy)-propyl]-1H-pyrazol-3-yl}-amide (203 mg, 0.307 mmol), isopropyl alcohol (2 mL), and ammonium hydroxide (2.5 mL) was microwaved at 130° C. for 15 min. 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-2-fluoro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carboxylic acid {1-[2-((S)-3-amino-2-hydroxy-propoxy)-2-methyl-propyl]-1H-pyrazol-3-yl}-amide (50.2 mg, 24.1%) as an white powder. HRMS (ES+) m/z Calcd for C33H40Cl2F2N6O3+H [(M+H)+]: 677.2580. found: 677.2577.
