Reaction Conditions

Reaction Steps

A mixture of 6-methoxy-7-(2-morpholinoethoxy)-4-phenoxyquinazoline (400 mg, 1.05 mmol) and 2M hydrochloric acid (10 ml) was heated at 100° C. for 2 hours and then allowed to cool. The mixture was neutralised with solid sodium hydrogen carbonate. Addition of methylene chloride gave a white precipitate which was collected by filtration, washed with acetone and dried to give 6-methoxy-7-(2-morpholinoethoxy)-3,4-dihydroquinazolin-4-one (320 mg, 100%).
