Using a procedure analogous to that described for Example 9, 4-chloro-6-methoxy-7-((1-methylpiperidin-4-yl)methoxy)quinazoline (0.13 g, 0.4 mmol), (prepared as described for the starting material in Example 10), was reacted with 6-hydroxy-2H-4H-1,4-benzoxazin-3-one (83 mg, 0.5 mmol), (J. Chem. Soc. C, 1971, 2696), to give 6-methoxy-7-((1-methylpiperidin-4-yl)methoxy)-4-(3-oxo-2H-4H-1,4-benzoxazin-6-yloxy)quinazoline (158 mg, 88%).
