Procedure
2M Hydrochloric acid (3 ml, 6 mmol) was added to a solution of 4-(1-diethoxymethyloxindol-3-yl)-6-methoxy-7-3-morpholinopropoxy)quinazoline (295 mg, 0.55 mmol), (prepared as described in Example 5), in ethanol (20 ml) at 80° C. The mixture was stirred for 45 minutes at 80° C. After cooling of the reaction mixture, partial evaporation of the solvents led to the crystallisation of the compound. The solid was collected by filtration, washed with ethanol and then ether and dried under vacuum at 50° C. to give 6-methoxy-7-(3-morpholinopropoxy)-4-(oxindol-3-yl)quinazoline as a hydrochloride salt (207 mg, 84%) as an orange solid.
