Procedure

10 ml of ethanol and 197 mg of sodium borohydride were added to 200 mg of 4-(α-ethoxycarbonyl-3,4-methylenedioxybenzyl)amino-6-chloroquinazoline. The obtained mixture was refluxed for 30 minutes, followed by the addition of 5 ml of water. The obtained mixture was concentrated under a reduced pressure, followed by the addition of 10 ml of water. The crystal thus precipitated was recovered by filtration. Thus, 30 mg of the title compound was obtained.
