Procedure

After dissolving 79 mg of 1-(tert-butoxycarbonyl)-4-[(2-fluorophenylthio)methyl]piperidine in 3 ml of chloroform, 42 mg of 3-chloroperbenzoic acid was added while cooling on ice, and the mixture was stirred for 30 minutes. Aqueous sodium thiosulfate solution was added to the reaction solution, and extraction was performed with ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate, and then the solvent was distilled off under reduced pressure. The residue was purified by NH silica gel column chromatography (solvent: n-hexane/ethyl acetate) to obtain the title compound (68 mg, 82% yield).
