Reaction Steps

A solution of 7-benzyloxy-4-(2-fluoro-5-methoxycarbonyloxy-4-methylanilino)-6-methoxyquinazoline (700 mg, 1.4 mmol) in DMF (10 ml), methanol (10 ml) and trichloromethane (10 ml) containing 10% palladium-on-charcoal (100 mg) was stirred under 1 atmosphere of hydrogen for 1 hour. After filtration and evaporation of the solvent, the residue was triturated with ether, filtered and dried under vacuum to give 4-(2-fluoro-5-methoxycarbonyloxy-4-methylanilino)-7-hydroxy-6-methoxyquinazoline (570 mg, 98%).
