Reaction Steps

A mixture of 7-hydroxy-6-methoxy-4-(2-methylindol-5-yloxy)quinazoline (322 mg, 1.00 mmol), (prepared as described in Example 49), potassium carbonate (414 mg, 3.00 mmol) and epibromohydrin (274 mg, 2.00 mmol) in DMF (7.0 ml) was stirred at 60° C. for 2 hours and allowed to cool to ambient temperature. The solvent was removed by evaporation and the residue taken up in dichloromethane (10 ml). An aliquot (5 ml) of this solution was treated with morpholine (48 μl, 0.6 mmol) and stirred for 24 hours at ambient temperature. The solvent was removed by evaporation, treated with water and stirred vigorously for 30 minutes. The precipitate was filtered, washed with water and dried. The resultant solid was stirred as a suspension in acetone, filtered, washed with diethyl ether and dried to give 7-(2-hydroxy-3-morpholinopropoxy)-6-methoxy-4-(2-methylindol-5-yloxy)quinazoline (127 mg, 27%).
