Procedure

In a solution of 0.24 g of methyl N-[4-[5-(3,5-dichlorophenyl)-5-trifluoromethyl-4,5-dihydroisoxazole-3-yl]-2-methylbenzoyl]carbamate synthesized in Synthetic Example 19 and 0.12 g of N-iodosuccinimide in 3 mL of N,N-dimethylformamide, 0.0112 g of palladium (II) acetate was added, and stirred under nitrogen atmosphere at 100° C. for 4 hours. After the completion of the reaction, the reaction mixture was poured in a solution of 0.03 g of sodium thiosulfate in 30 mL of water, and extracted with ethyl acetate (30 mL×1), the organic phase was dehydrated with and dried over saturated sodium chloride aqueous solution and then anhydrous sodium sulfate, and the solvent was distilled off under reduced pressure. The residue was purified with silica gel column chromatography that was eluated with ethyl acetate-hexane (gradient of 0:1 to 3:2) to obtain 0.11 g of the aimed product as colorless resinous substance.
