m-Chloroperbenzoic acid → HCID 10405045, compound

Participants

Reaction Steps

A solution of 1.20 g (6.95 mmol) of m-chloroperbenzoic acid in 30 ml of chloroform was dropped into a solution of 1.80 g (5.53 mmol) of 4-(3,4-methylenedioxybenzyl)amino-6-methylthioquinazoline in 100 ml of chloroform under cooling with ice and stirring. The obtained mixture was stirred under cooling with ice for several hours, washed with a saturated aqueous solution of sodium hydrogencarbonate, dried over anhydrous magnesium sulfate and filtered. The filtrate was purified by silica gel column chromatography (ethyl acetate/acetone) and recrystallized from chloroform/n-hexane to give 1.51 g of the title compound as a pale-yellow crystal.
