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 isopropylamine (0.29 ml, 4.65 mmol) in DMF (5 ml) was stirred at 100° 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-(isopropylamino)propoxy)-6-methoxy-4-(3-methylindol-5-yloxy)quinazoline (307 mg, 75%).
