Versuchsvorschrift

2.0 g of 5-acetylamino-1-{2-fluoro-4-methyl-5-(2,2,2-trifluoroethylthio)phenyl}-3-hydroxypyrazole was dissolved in 30 mL of dichloromethane, 2.18 g of pyridine was added, and the above prepared crude (perfluoropentyl)phenyliodonium trifluoromethanesulfonate was added at room temperature until 5-acetylamino-1-{2-fluoro-4-methyl-5-(2,2,2-trifluoroethylthio)phenyl}-3-hydroxypyrazole disappeared (disappearance was confirmed by thin layer chromatography). Then, the solvent was distilled off under reduced pressure, a saturated salt solution was added, extraction with ethyl acetate was carried out, the organic layer was dried over anhydrous sodium sulfate, the solvent was distilled off under reduced pressure, and the obtained residue was purified by column chromatography (developing solvent ethyl acetate:hexane=1:3) to obtain 0.64 g of 5-acetylamino-1-{2-fluoro-4-methyl-5-(2,2,2-trifluoroethylthio)phenyl}-3-(1,1,2,2,3,3,4,4,5,5,5-undecafluoropentyloxy)pyrazole.
