実験手順
According to method of U.S. Pat. No. 3,781,438, 2 g of methyl 3-(4-methylphenyl)-3-oxopropanoate was dissolved in methanol, slightly excessive hydroxylamine hydrochloride and equivalent amount of sodium hydroxide were added, the mixture was heated to reflux. 3 hr later, the reaction was traced by Thin-Layer Chromatography, after the reaction, water was added to the reaction mixture, extracted with ethyl acetate, The combined organic extracts were dried and concentrated to obtain 3-(4-methylphenyl)isoxazol-5-ol as solid (compound III-3).
