Procedure

0.6 g of 5-acetylamino-1-{2-fluoro-4-methyl-5-(2-chloro-2,2-difluoroethylthio)phenyl}-3-(2,2,3,3,3-pentafluoropropoxy)pyrazole was dissolved in 20mL of chloroform, and 0.3 g of m-chloroperbenzoic acid (purity: 75%) was added under cooling with ice. After stirring for 30 minutes under cooling with ice, the solution was washed with an aqueous sodium thiosulfate solution and then washed with an aqueous potassium carbonate solution, and dried over anhydrous magnesium sulfate. Then, the solvent was distilled off under reduced pressure, the obtained residue was purified by silica gel column chromatography (developing solvent ethyl acetate:hexane=1:2) to obtain 0.6 g of the title compound.
