Nitrogen was bubbled through a mixture of 4-chloro-6-methoxy-7-(2-piperidinoethoxy)quinazoline (400 mg, 1.24 mmol), (prepared as described for the starting material in Example 180), potassium carbonate (500 mg, 3.62 mmol), 5-hydroxy-1-methylindole (231 mg, 1.57 mmol), (prepared as described for the starting material in Example 291), and DMA (5.0 ml) for 5 minutes. The mixture was then stirred at 90° C. for 3 hours under an atmosphere of nitrogen and then allowed to cool to ambient temperature. The reaction mixture was filtered and the filtrate evaporated in vacuo. The residue was purified by trituration with methanol to give 6-methoxy-4-(1-methylindol-5-yloxy)-7-(2-piperidinopropoxy)quinazoline (447 mg, 83%).
