Procedure

Using an analogous procedure to that described for Example 9, 4-chloro-6-methoxy-7-(3-morpholinopropoxy)quinazoline (134 mg, 0.4 mmol), (prepared as described for the starting material in Example 2), was reacted with 3-(3-pyridyl)-4,5-dihydro-1H-pyrazol-5-one (161 mg, 1 mmol) in the presence of sodium hydride (40 mg, 1 mmol, prewashed with THF) in DMF (3 ml) to give 6-methoxy-7-(3-morpholinopropoxy)-4-(5-(3-pyridyl)pyrazol-3-yloxy)quinazoline (110 mg, 59%).
