Participants

Reaction Steps

In a solution of 2.6 g of methyl N-[4-[5-(3,5-dichlorophenyl)-5-trifluoromethyl-4,5-dihydroisoxazol-3-yl]-2-methylbenzoyl]glycine (Compound of the present invention No. 5-128) synthesized similarly to Synthetic Example 5 in 10 ml of methanol, a solution of 1.0 g of potassium hydroxide in 10 ml of water was added with stirring at room temperature, and stirred at the same temperature for further 1 hour. After the completion of the reaction, 10 ml of 12N hydrochloric acid was added and extracted with ethyl acetate (50 ml×1), the organic phase was dehydrated with saturated sodium chloride aqueous solution and dried over anhydrous sodium sulfate, and then the solvent was distilled off under reduced pressure to obtain 2.4 g of the aimed product as pale yellow resinous substance.
