N-chlorosuccinimide (0.06 g) was added to N-({4-[(hydroxyimino)methyl]naphthalen-1-yl}methyl)acetamide (0.1 g) in N,N-dimethylformamide (10 ml), and the reaction mixture was stirred at room temperature for 2 hours. 1,2-dichloro-3-(trifluoromethyl)-5-[1-(trifluoromethyl)ethenyl]benzene (0.75 g) and potassium bicarbonate (0.13 g) was added to the reaction mixture, and the mixture was stirred at room temperature for 8 hours. Water was poured into the reaction mixture, and it was extracted with ethyl acetate. The organic layer was washed with brine, and dried over Magnesium sulfate anhydrous. The solvent was evaporated under the reduced pressure, and the residue was purified with silicagel columnchromatography to get N-[(4-{5-[3,4-dichloro-5-(trifluoromethyl)phenyl]-5-(trifluoromethyl)-4,5-dihydroisoxazol-3-yl}naphthalen-1-yl)methyl]acetamide (0.1 g).
