실험 절차

In a solution of 10.79 g of 4-[5-(3,5-dichlorophenyl)-5-trifluoromethyl-4,5-dihydroisoxazole-3-yl]-2-methylbenzoic acid ethyl ester in 50 ml of ethanol and 10 ml of water, a solution of 2.0 g of sodium hydroxide in 10 ml of water was slowly added with stirring at room temperature. Then, the reaction mixture was stirred at 80° C. for 2 hours, after the completion of the reaction, ethanol was distilled off under reduced pressure. The residue was adjusted to pH 1-2 with concentrated hydrochloric acid with stirring at 50° C., then continued to stir at the same temperature for 1 hour and then at 5° C. for 1 hour. Precipitated crystal was filtered off, washed with water and dried to obtain 9.36 g of the aimed product as white crystal.
