m-Chloroperbenzoic acid → HCID 57736477, compound

Participants

Reaction Steps

3-Chloroperbenzoic acid (259 mg, 0.98 mmol) was added to a solution of 5-[[(4-chlorophenyl)thio](2,5-difluorophenyl)methyl]-4-methylpyridine-2-carboxamide (395 mg, 0.98 mmol) in methylene chloride (10 ml) at 0° C. After stirring for 14 days at room temperature, the reaction mixture was washed with 1 N aqueous sodium hydroxide. The organic layer was dried over anhydrous sodium sulfate and filtered, then the filtrate was concentrated under reduced pressure, and the resulting residue was subjected to flash silica gel chromatography. The fraction obtained from an elution with hexane:ethyl acetate=1:1 was concentrated under reduced pressure, and the resulting residue was washed with a mixed solvent of ethanol and diethyl ether, and collected by filtration, thus to obtain the title compound (243 mg, 0.58 mmol, 59%) as a white solid.
