Reaction Steps

5.00 g (17.3 mmol) of 2,4-dichloro-6,7,8-trimethoxyquinazoline was suspended in 100 ml of methanol, followed by the gradual addition of 1.5 g of sodium hydride. The obtained mixture was heated under reflux. After several hours, the reaction mixture was concentrated under a reduced pressure, followed by the addition of water. The crystal thus precipitated was recovered by filtration, washed with water and air-dried to give 4.80 g of the title compound as a pale-pink crystal.
