Procedure

A mixture of 7-(2,3-epoxypropoxy)-6-methoxy-4-(2-methylindol-5-yloxy) quinazoline (100 mg, 0.27 mmol), (prepared as described for the starting material in Example 162), and diethylamine (100 ul, 0.8 mmol) in DMF (4 ml) was heated at 70° C. for 24 hours. The solvent was removed by evaporation and the residue was purified by silica column chromatography eluting with dichloromethane/methanol/0.880 aqueous ammonia (100/8/1). The relevant fractions were evaporated to dryness then the residue treated with a little dichloromethane and dried under high vacuum to give 7-(3-(N,N-diethylamino)-2-hydroxypropoxy)-6-methoxy-4-(2-methylindol-5-yloxy)quinazoline (55 mg, 46%) as a white foam.
