A suspension of 4-chloro-6-methoxy-7-(3-pyrrolidin-1-ylpropoxy)quinazoline (10 mg, 0.34 mmol), (prepared as described for the starting material in Example 9), and 2,3-dimethyl-5-hydroxyindole (66 mg, 0.41 mmol), (Arch. Pharm. 1972, 305, 159), in DMF (1.5 ml) containing potassium carbonate (70 mg, 0.51 mmol) was heated at 100° C. for 2 hours. After cooling, the residue was purified by chromatography, eluting with methanol/methylene chloride (1/9) followed by 2.5M ammonia in methanol/methanol/methylene chloride (5/10/85) to give 4-(2,3-dimethylindol-5-yloxy)-6-methoxy-7-(3-pyrrolidin-1-ylpropoxy)quinazoline (50 mg, 33%).
