Reaction Steps
A mixture of 7-hydroxy-6-methoxy-4-(2-methylindol-5-yloxy)quinazoline (1.89 g, 5.90 mmol), (prepared as described in Example 49), potassium carbonate (2.43 g, 17.6 mmol) and epibromohydrin (1.61 g, 11.7 mmol) in DMF (40 ml) was stirred at 60° C. for 2 hours and allowed to cool to ambient temperature. The insoluble inorganic material was removed by filtration and the solvent was removed by evaporation. The residue was triturated with diethyl ether, filtered, washed with further diethyl ether and dried to give 7-(2,3-epoxypropoxy)-6-methoxy-4-(2-methylindol-5-yloxy)quinazoline (1.97 g, 89%).
