Conditions

Temperature
50 °C

Procedure

20 ml of ethanol and 2.61 ml of a 1N aqueous solution of sodium hydroxide were added to 389 mg of 2-(N-(3-ethoxycarbonylpropyl)-N-methoxyamino]-4-(3,4-methylenedioxybenzyl)amino-6-cyanoquinazoline. The obtained mixture was stirred at room temperature for 4 hours and at 50° C. for 10 minutes and neutralized with 1N hydrochloric acid. The crystals precipitated were recovered by filtration, purified by silica gel column chromatography (chloroform/methanol) and recrystallized from ethanol/acetone/water to give 305 mg of the title compound.
