Reaction Steps

A mixture of (2R)-6-methoxy-4-(2-methylindol-5-yloxy)-7-(oxiran-2-ylmethoxy)quinazoline (300 mg, 0.79 mmol), (prepared as described for the starting material in Example 269), and diethylamine (0.25 ml, 2.38 mmol) in DMF (10 ml) was stirred at 70° 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, gradient elution (dichloromethane, 5% methanol/95% dichloromethane, dichloromethane/methanol/0.88 ammonia (100/8/1)) to give (2R)-7-(3-(N,N-diethylamino)-2-hydroxypropoxy)-6-methoxy-4-(2-methylindol-5-yloxy)quinazoline (288 mg, 81%).
