Reaction Steps

0.60 g of hydroxylamine hydrochloride and 3.0 ml of a 1N aqueous solution of sodium hydroxide were added to a solution of 1.00 g (2.93 mmol) of 2-formyl4-(3,4-methylenedioxybenzyl)amino-6-chloroquinazoline in 30 ml of ethanol. The obtained mixture was stirred at 60° C. for 30 minutes and cooled by allowing to stand. The crystal thus precipitated was recovered by filtration, washed with ethanol and n-hexane and air-dried to give 1.00 g of the title compound as a white crystal.
