Reaction Steps

1.5 g of 1-{2-fluoro-4-methyl-5-(2,2,2-trifluoroethylsulfinyl)phenyl}-5-hydroxymethyl-3-(2,2,3,3,3-pentafluoropropoxy)pyrazole was dissolved in 30 mL of chloroform and 10 mL of methanol, and 3.0 g of manganese dioxide was added, followed by stirring at room temperature for 12 hours. Then, the reaction solution as subjected to filtration, the filtrate was distilled under reduced pressure, and the obtained residue was purified by column chromatography (developing solvent ethyl acetate:hexane=1:4) to obtain 1.02 g of 1-{2-fluoro-4-methyl-5-(2,2,2-trifluoroethylthio)phenyl}-5-formyl-3-(2,2,3,3,3-pentafluoropropoxy)pyrazole.
