実験手順
20 ml of a 10% solution of ammonia in ethanol was added to 200 mg of 4-(α-ethoxycarbonyl-3,4-methylenedioxybenzyl)amino-6-chloroquinazoline. The obtained mixture was stirred at room temperature for 3 days. The crystal thus precipitated was recovered by filtration. Thus, 60 mg of the title compound was obtained.
