3-bromo-4-{[4-chloro-5H-1,2,3-dithiazol-5-ylidene]amino}-N-[2-ethyl-6-methyl-4-(1,1,1,2,3,3,4,4,4-nonafluorobutan-2-yl)phenyl]benzamide (0.195 g) and copper(I) iodide (0.057 g) were suspended in pyridine (5 ml), and irradiated(150° C., 20 minutes). After cooling, to the reaction mixture was added ethyl acetate. The mixture was washed with 1N hydrochloric acid and 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 residue was 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]-1,3-benzothiazole-6-carboxamide (0.076 g, 49%).
