실험 절차
11.7 g of aniline are added dropwise to 10.0 g of 3-ethylisoxazole-5-carbonyl chloride in 150 ml of dichloromethane, while cooling with ice. The mixture is stirred overnight at room temperature, water and concentrated hydrochloric acid are added and the organic phase is separated off, washed with sodium bicarbonate solution and evaporated down to give 11.8 g of 3-ethylisoxazole-5-carboxanilide as colorless crystals of melting point 122°-124° C.
