Reaction Steps
20 ml of N,N-dimethylformamide and 221 mg of sodium thiomethoxide were added to 1 g of 2,6-dichloro-4-(3,4-methylenedioxybenzyl)aminoquinazoline. The obtained mixture was stirred at 110° C. for one hour, neutralized with 1N hydrochloric acid and stirred at room temperature for one hour, followed by the addition of water. The crystals thus precipitated were recovered by filtration to give 780 mg of the title compound.
