Reaction Steps

A mixture of 4-chloro-6-methoxy-7-(3-piperidinopropoxy)quinazoline (222 mg, 0.662 mmol), (prepared as described for the starting material in Example 67), and 6-fluoro-5-hydroxyindole (120 mg, 0.794 mmol), (prepared as described for the starting material in Example 242), in DMF (3 ml) containing potassium carbonate (137 mg, 0.993 mmol) was heated at 95° C. for 3.5 hours. After cooling the mixture was poured onto water and extracted with ethyl acetate. The organic layers were washed with water, brine, dried (MgSO4) and evaporated. The residue was triturated with ether, filtered and dried under vacuum to give 4-(6-fluoroindol-5-yloxy)-6-methoxy-7-(3-piperidinopropoxy)quinazoline (139 mg, 46%).
