Reaction Steps

30 ml of phosphorus oxychloride was added to a suspension of 1.50 g (5.06 mmol) of 2-benzyloxymethyl-6-methoxyquinazolin-4(3H)-one in 75 ml of acetonitrile. The obtained mixture was heated under reflux. After one hour, the reaction mixture was distilled under a reduced pressure to remove the solvent and the obtained residue was dissolved in chloroform. The obtained solution was washed with a saturated aqueous solution of sodium hydrogen-carbonate. The organic layer was dried over anhydrous magnesium sulfate and filtered. The filtrate was distilled under a reduced pressure to remove the solvent. The residue was purified by silica gel column chromatography (ethyl acetate/n-hexane) to give 1.10 g of the title compound as a yellow crystal.
