Reaction Steps

In a solution of 0.06 g of 4-[5-(3,5-dichlorophenyl)-5-trifluoromethyl-4,5-dihydroisoxazole-3-yl]-2-methylamino-N-(2-pyridylmethyl)benzoic acid amide (Compound of the present invention No. 5-332) synthesized similarly to Synthetic Example 18 in 5 ml of dichloromethane, 0.03 g of chloromethylether was added, and stirred at the same temperature for 15 hours After the completion of the reaction, the solvent was distilled off under reduced pressure, and the residue was purified with silica gel column chromatography that was eluated with ethyl acetate-hexane (3:1) to obtain 0.04 g of the aimed product as colorless oily substance.
