Reaction Steps

A mixture of (2R)-4-(indol-5-yloxy)-6-methoxy-7-(oxiran-2-ylmethoxy)quinazoline (100 mg, 0.28 mmol), (prepared as described for the starting material in Example 292), and isopropylamine (1.0 ml) in THF (10 ml) was stirred at 75° C. for 18 hours under an atmosphere of nitrogen and then allowed to cool to ambient temperature. The mixture was filtered and the filtrate evaporated in vacuo. The residue was purified by silica gel chromatography, gradient elution with dichloromethane/methanolic ammonia (7M) (100/0 to 90/10) to give (2R)-7-(2-hydroxy-3-(isopropylamino)propoxy)4-(indol-5-yloxy)-6-methoxyquinazoline (82 mg, 68%).
