Procedure

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 (43.6 mg, 0.066 mmol), isopropyl alcohol (2 mL), diisopropylethyl amine (0.1 mL, 0.56 mmol) and 3-amino-1-propanol (0.1 mL, 1.3 mmol) was microwaved at 130° C. for 15 min. 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-[(R)-2-hydroxy-3-(3-hydroxy-propylamino)-propoxy]-2-methyl-propyl}-1H-pyrazol-3-yl)-amide (10.1 mg, 20.8%) as an off-white powder. HRMS (ES+) m/z Calcd for C36H46Cl2F2N6O4S+H [(M+H)+]: 735.2999. found: 735.2998.
