Participants

Reaction Steps

In a solution of 0.35 g of 4-[5-(3,5-dichlorophenyl)-5-trifluoromethyl-4,5-dihydroisoxazol-3-yl]-2-methyl-N-(2-pyridylmethyl) benzoic acid amide (Compound of the present invention No. 5-234) synthesized similarly to Synthetic Example 5 in 20 ml of N,N-dimethylformamide, 0.04 g of 55% oily sodium hydride was added under cooling with ice with stirring, and stirred at the same temperature for 30 minutes. Then, 0.12 g of methyl iodide was added and thereafter the temperature was raised to room temperature, and continued to stir at the same temperature for further 2 hours. After the completion of the reaction, the reaction mixture was diluted with 80 ml of ethyl acetate, washed with water (50 ml×2), dehydrated with saturated sodium chloride aqueous solution and dried over anhydrous magnesium sulfate, and then the solvent was distilled off under reduced pressure. The residue was purified with high performance liquid chromatography that was eluated with acetonitrile-water (85:15) to obtain 0.25 g of the aimed product as colorless resinous substance.
