실험 절차
4-Chloromethyl-benzoyl chloride (18.9 g) (0.1 mol) and 13.8 g (0.2 mol) of hydroxylamine hydrochloride are suspended in 200 ml of water and 150 ml of diethyl ether. 25.2 g (0.3 mol) of sodium hydrogen carbonate are added while stirring. After 30 minutes the product is filtered off under suction and washed with water and diethyl ether. After drying in a high vacuum at room temperature there are obtained 17 g of white α-chloro-N-hydroxy-p-toluamide of m.p. 120°-145° C. (dec.).
