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 (87.5 mg, 0.133 mmol), isopropyl alcohol (2 mL), and methylamine (1.0 mL, 2 mmol, 2 M in methanol; old bottle) was microwaved at 130° C. for 15 min. The solvent evaporated under reduced pressure. The resulting oil was 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)-2-hydroxy-3-methylamino-propoxy)-2-methyl-propyl]-1H-pyrazol-3-yl}-amide (14.9 mg, 16.2%) as an off-white powder. HRMS (ES+) m/z Calcd for C34H42Cl2F2N6O3S+H [(M+H)+]: 691.2737. found: 691.2731.
