Reaktionsschritte

A solution of 39.4 g of 2-fluoroaniline in 32.4 ml of concentrated hydrochloric acid and 215 ml of water and then a solution of 77.6 g of hydroxylamine hydrochloride in 355 ml of water were added to a mixture of 886 g of sodium sulfate hydrated with 10 moles of water, 64.55 g of chloral hydrate and 850 ml of water and the mixture was heated to reflux with stirring over 45 minutes and reflux was maintained for 5 minutes. The mixture was cooled to 25° C. and held there for 45 minutes. The product was washed with water and dried at room temperature and then at 70° C. under reduced pressure to obtain 56.8 g of N-(2-fluorophenyl)-2-hydroxyimino-acetamide melting at 120° C.
