2-Cyano-N-[2-ethyl-6-methyl-4-(1,1,1,2,3,3,4,4,4-nonafluorobutan-2-yl)phenyl]quinoline-6-carboxamide (240 mg) was dissolved in dichloromethane, added with urea-hydrogen peroxide adduct (85 mg) and trifluoroacetic anhydride (190 mg), and stirred at room temperature for 20 hours. The reaction solution was concentrated under the reduced pressure, and the resulting residues were dissolved in ethyl acetate. The solution was washed with water and dried over anhydrous magnesium sulfate. The drying agent was filtered off and the solvent was removed by distillation under the reduced pressure. The resulting residues were purified by column chromatography to obtain 2-cyano-N-[2-ethyl-6-methyl-4-(1,1,1,2,3,3,4,4,4-nonafluorobutan-2-yl)phenyl]quinoline-6-carboxamide-1-oxide (0.20 g, 81%).
