Procedure

A mixture of (2S)-4-(indol-5-yloxy)-6-methoxy-7-(oxiran-2-ylmethoxy)quinazoline (100 mg, 0.28 mmol), and pyrrolidine (60 mg, 0.84 mmol) in DMF (5 ml) was stirred at 75° C. for 3 hours under an atmosphere of nitrogen and then allowed to cool to ambient temperature. The solvents were removed in vacuo and the residue purified on silica gel, gradient elution with dichloromethane, dichloromethane/methanol (95/5), dichloromethane/methanolic ammonia (7M) (98/2 to 90/10), to give (2S)-7-(2-hydroxy-3-(pyrrolidin-1-yl)propoxy)-4-(indol-5-yloxy)-6-methoxyquinazoline (114 mg, 92%).
