Procedure
0.20 g (0.461 mmol) of 3-[7-chloro-5-fluoro-2-(1-methylthiopropyl)benzofuran-4-yl]-1-methyl-6-trifluoromethyl-2-(1H)-pyridone was dissolved in 15 ml of methanol, and 5 ml of water and 0.57 g (0.922 mmol) of Oxone were added thereto, followed by stirring at room temperature for 2 hours. Insoluble substances were removed by filtration. Then, methanol was distilled off under reduced pressure, and the obtained residue was poured into water and extracted with ethyl acetate. After washing with water, the organic layer was dried over anhydrous magnesium sulfate. Ethyl acetate was distilled off under reduced pressure. Then, the obtained residue was purified by silica gel column chromatography to obtain 0.18 g (yield: 85%) of the desired product. Melting point: 146-148° C.
