Participants

Reaction Steps

To a solution of 0.22 g (0.33 mmol) (RS)-2-(3,5-bis-trifluoromethyl-phenyl)-N-[4′-(4-fluoro-2-methyl-phenyl)-4-methanesulfinylmethyl-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-5′-yl]-N-methyl-isobutyramide in 5 ml dichloromethane were added 142 mg (70%, 0.58 mmol) 3-chloroperbenzoic acid at 0° C. After completed addition, the reaction mixture was allowed to warm to room temperature and stirred over night. An aqueous solution of sodium hydrogensulfite was added and the mixture was stirred for 10 min. Basification with 1 N aqueous sodium hydroxide solution was followed by extraction with three portions of dichloromethane. The combined organic extracts were dried over sodium sulphate and concentrated. Flash column chromatography gave 0.13 g (55%) of the title compound as a white solid.
