Using an analogous procedure to that described in Example 6, 7-benzyloxy-4-chloro-6-methoxyquinazoline hydrochloride (1.55 g, 5.15 mmol), (prepared, for example, as described in WO 97/22596, Example 1), was reacted with 2-fluoro-4-methylaniline (700 mg, 5.67 mmol) in isopropanol (90 ml) containing 6.2M hydrogen chloride in isopropanol (80 μl, 0.51 mmol) to give 7-benzyloxy-4-(2-fluoro-4-methylanilino)-6-methoxyquinazoline hydrochloride (2 g, 91%).
