Versuchsvorschrift
3.0 g of 5-acetylamino-1-{2-fluoro-4-methyl-5-(2,2,2-trifluoroethylthio)phenyl}-3-hydroxypyrazole was dissolved in 40 mL of dimethylformamide, 25 g of triethylamine was added, and stirring was carried out at 50° C. for 3 hours while trifluoromethyl trifluorovinyl ether was blown. To this solution, ethyl acetate was added, the solution was washed with a saturated aqueous solution of citric acid, 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 (developing solvent ethyl acetate:hexane=1:4) to obtain 1.71 g of 5-acetylamino-1-{2-fluoro-4-methyl-5-(2,2,2-trifluoroethylthio)phenyl}-3-{1,1,2-trifluoro-2-(trifluoromethoxy)ethoxy}pyrazole.
