Procedure

A mixture of (2S)-6-methoxy-4-(2-methylindol-5-yloxy)-7-(oxiran-2-ylmethoxy)quinazoline (250 mg, 0.66 mmol), and pyrrolidine (1.5 ml) in THF (10 ml) was stirred at 75° C. for 3 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 chromatographyusing gradient elution with dichloromethane/methanolic ammonia (7M) (100/0 to 90/10) to give (2S)-7-(2-hydroxy-3-(pyrrolidin-1-yl)propoxy)-6-methoxy-4-(2-methylindol-5-yloxy)quinazoline (106 mg, 36%).
