実験手順

0.5 g of 5-acetylamino-1-{2-fluoro-4-methyl-5-(2,2,2-trifluoroethylthio)phenyl}-3-hydroxypyrazole was dissolved in 10 mL of dimethylsulfoxide, and 0.28 g of potassium carbonate and 1.0 g of 2,2-difluoro-2-{2-trifluoromethoxy-(1,1,2,2-tetrafluoroethoxy)}ethyl nonafluorobutylsulfonate were added, followed by stirring at room temperature for 12 hours. After completion of the reaction, the reaction solution was poured into water, extraction with ethyl acetate was carried out, and after washing with a saturated salt solution, the organic layer was dried over anhydrous magnesium sulfate, the solvent was distilled off under reduced pressure, and the obtained residue was purified by column chromatography (ethyl acetate:hexane=1:4) to obtain 0.67 g of 5-acetylamino-3-[2,2-difluoro-2-{2-trifluoromethoxy-(1,1,2,2-tetrafluoroethoxy)}ethoxy]-1-{2-fluoro-4-methyl-5-(2,2,2-trifluoroethylthio)phenyl}pyrazole.
