Procedure

A mixture of (2R)-6-methoxy-4-(2-methylindol-5-yloxy)-7-(oxiran-2-ylmethoxy)quinazoline (300 mg, 0.79 mmol), and 1-methylpiperazine (0.26 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) and evaporated in vacuo to give (2R)-7-(2-hydroxy-3-(4-methylpiperazin-1-yl)propoxy)-6-methoxy-4-(2-methylindol-5-yloxy)quinazoline (344 mg, 91%).
