실험 절차
A mixture of (2R)-4-(indol-5-yloxy)-6-methoxy-7-(oxiran-2-ylmethoxy)quinazoline (300 mg, 0.83 mmol), (prepared as described for the starting material in Example 292), and diisopropylamine (1.35 ml, 9.7 mmol) in DMF (5 ml) was stirred at 70° C. for 19 hours under an atmosphere of nitrogen then allowed to cool to ambient temperature. The solvents were removed in vacuo and the residue purified on silica gel using gradient elution with dichloromethane, dichloromethane/methanol (95/5), dichloromethane/methanolic ammonia (7M) (98/2 to 90/10) to give (2R)-7-(2-hydroxy-3-((N,N-diisopropyl)amino)propoxy)-4-(indol-5-yloxy)-6-methoxyquinazoline (343 mg, 86%).
