Procedure

To a solution of 5-(2,6-dimethyl-4-pyridyl)-4-(3-methylphenyl)-2-[4-(methylthio)phenyl]-1,3-thiazole (0.41 g, 1.0 mmol) in N,N-dimethylformamide (15 mL) was added m-chloroperbenzoic acid (0.25 g, 1.0 mmol), and the mixture was stirred for 1 hour at room temperature. A 8N aqueous sodium hydroxide solution was poured into the reaction mixture, and extracted with ethyl acetate. The extracted solution was washed with brine, dried, then, the solvent was distilled off. The residue was purified by column chromatography (filler: Chromatorex NH DM1020 (trade name, manufactured by Fuji Silysia Chemical Lte.), hexane-ethyl acetate=1:2), to obtain a title compound (0.41 g, yield 97%).
