실험 절차

To a suspension of 7.11 g of N-benzylisatin in 75 ml of ethanol was added a solution of 3.84 g of hydroxylamine hydrochloride and 3.84 g of sodium acetate in 500 ml of water. The mixture was stirred at room temperature for 1 hour, followed by concentration. The residue was washed with water and recrystallized from ethanol to give 6.11 g (81%) of the title compound as yellow crystals.
