In a suspended solution of 0.13 g of N-aminomethyl-4-[5-(3,5-dichlorophenyl)-5-trifluoromethyl-4,5-dihydroisoxazol-3-yl]-2-methyl benzoic acid amide hydrochloride synthesized in Synthetic Example 32 in 4 ml of dichloromethane, 0.03 g of methyl chloroformate and 0.08 g of triethyl amine were added with stirring at room temperature, and stirred at room temperature for 3 hours. After the completion of the reaction, the solvent was distilled under reduced pressure, the residue was purified with silica gel column chromatography that was eluated with ethyl acetate-hexane (1:1) to obtain 0.06 g of the aimed product as colorless resinous substance.
