A mixture of 4-(7-azaindol-5-yloxy)-6-methoxy-7-(3-piperazin-1-ylpropoxy)quinazoline (87 mg, 0.2 mmol), (prepared as described for the starting material in Example 34), iodoacetamide (41 mg, 0.22 mmol) and N,N-diisopropylethylamine (26 mg, 0.22 mmol) in acetonitrile (5 ml) was stirred at reflux for 1 hour and allowed to cool to ambient temperature. The crude reaction mixture was loaded onto a silica column and eluted using methylene chloride/methanol (saturated with ammonia) (92/8) solvent. The relevant fractions were combined and evaporated under vacuum to give a residue which was triturated with acetone, filtered and dried to give 4-(7-azaindol-5-yloxy)-7-[3-(4-carbamoylmethyl)piperazin-1-yl)propoxy]-6-methoxyquinazoline (62 mg, 63%).
