N-[2-Bromo-4-(1-bromo-1,1,2,3,3,3-hexafluoropropan-2-yl)-6-(difluoromethoxy)phenyl]-quinoline-6-carboxamide-1-oxide (0.41 g) was dissolved in tetrahydrofuran (50 ml), added with trimethylsilylnitrile (0.23 g) and 1,8-diazabicyclo[5.4.0]undec-7-ene (0.39 g), and stirred at 60° C. for 5 hours. Water was added to the reaction solution and extraction was carried out twice using ethyl acetate. The organic phases were combined and washed with water, and dried over anhydrous magnesium sulfate. The drying agent (anhydrous magnesium sulfate) was removed by filtration and the solvent was distilled off under the reduced pressure. The resulting residues were purified by column chromatography to obtain N-[2-bromo-4-(1-bromo-1,1,2,3,3,3-hexafluoropropan-2-yl)-6-(difluoromethoxy)phenyl]-2-cyanoquinoline-6-carboxamide (0.15 g, 36%).
