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-((R)-1-oxiranylmethoxy)-propyl]-1H-pyrazol-3-yl}-amide (0.69 g, 1.04 mmol), isopropyl alcohol (2 mL), and dimethylamine (1.04 mL, 2.08 mmol, 2 M in THF) was microwaved at 130° C. for 15 min. The mixture was extracted with dichloromethane and water. The organic layer was separated and the solvent evaporated under reduced pressure. The resulting oil was purified by column chromatography (50% ethyl acetate/heptane) 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-((R)-3-dimethylamino-2-hydroxy-propoxy)-2-methyl-propyl]-1H-pyrazol-3-yl)-amide (147.2 mg, 20.05%) as a white powder. HRMS (ES+) m/z Calcd for C35H44Cl2F2N6O3S+H [(M+H)+]: 705.2893. found: 705.2893.
