Procedure
To a mixture 23.0 g of ethyl 4-methanesulfonamidobenzoylacetate, 5.8 g of hydroxylamine hydrochloride, and 35 ml of methanol, 8.2 g of pottasium acetate was added, and the mixture was refluxed for 30 minutes while being heated. The reaction mixture was poured into 210 ml of water, and the precipitated crystals were collected by filtering and dried, thereby obtaining 1.39 of 3-(4-methanesulfonamidophenyl)isoxazolin-5-one.
