Methanol → HCID 18796797, compound

Participants

Reaction Steps

40 ml of a 1.0 M solution of boron trichloride in methylene chloride was dropped into a solution of 2.00 g (6.37 mmol) of 4-(3,4-methylenedioxybenzyl)amino-6-chloroquinazoline in 150 ml of chloroform under stirring at room temperature. The obtained mixture was stirred at room temperature for 2 days, followed by the addition of methanol, and the obtained mixture was distilled under a reduced pressure to remove the solvent. This procedure was repeated twice. The crystals thus precipitated were washed with methanol and recrystallized from ethanol to give 1.53 g of the title compound as a yellow crystal.
