To a solution of 0.100 g (0.180 mmol) of N-(2-bromo-4-(perfluoropropan-2-yl)-6-(trifluoromethyl)phenyl)-6-chloropicoline amide in 5 ml of 1,4-dioxane were added 0.00600 g (0.0360 mmol) of copper sulfate and 0.140 g (1.80 mmol) of a 40% aqueous methylamine solution, followed by stirring at an oil bath temperature 80° C. for 3 hours under an enclosed condition. The reaction liquid was returned to room temperature and opened, and water and ethyl acetate were added thereto. The organic layer was washed with water and saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure and the obtained residue was purified by silica gel column chromatography (eluent solvent; hexane:ethyl acetate=2:1) to prepare 0.0700 g (yield 69%) of a target compound.
