A mixture of (2R)-6-methoxy-4-(3-methylindol-5-yloxy)-7-(oxiran-2-ylmethoxy)quinazoline (350 mg, 0.93 mmol), (prepared as described in Example 278), and morpholine (0.24 ml, 2.78 mmol) in DMF (5 ml) was stirred at 60° C. for 24 hours and allowed to cool to ambient temperature. The solvents were removed in vacuo and the residue purified by silica column chromatography using gradient elution (dichloromethane, 5% methanol/95% dichloromethane, methanol/dichloromethane/0.880 saturated aqueous ammonia (100/8/1)) to give (2R)-7-(2-hydroxy-3-morpholinopropoxy)-6-methoxy-4-(3-methylindol-5-yloxy)quinazoline (398 mg, 93%).
