Procedure

Using an analogous procedure to that described in Example 36, 4-(2-fluoro-5-methoxycarbonyloxy-4-methylanilino)-7-hydroxy-6-methoxyquinazoline hydrochloride (224 mg, 0.6 mmol), (prepared as described for the starting material in Example 22), was treated with 4-bromomethyl-1,2-difluorobenzene (149 mg, 0.72mmol) to give 7-(3,4-difluorobenzyloxy)-4-(2-fluoro-5-hydroxy-4-methylanilino)-6-methoxyquinazoline hydrochloride (90 mg, 31%).
