반응 단계
10 ml of ethanol, 5 ml of water and 820 mg of sodium hydroxide were added to 1 g of 2-(4-ethoxy-carbonylpiperidino)-4-(3,4-methylenedioxybenzyl)amino-6-chloroquinazoline. The obtained mixture was refluxed for 20 minutes, concentrated under a reduced pressure and neutralized with 1N hydrochloric acid. The crystals thus precipitated were recovered by filtration to give 920 mg of the title compound.
