A solution of 4-chloro-6-methoxy-7-(3-methylsulphonylpropoxy)quinazoline (200 mg, 0.6 mmol), (prepared as described for the starting material in Example 50), and 6hydroxyindole (97 mg, 0.73 mmol) in DMF (3 ml) containing potassium carbonate (125 mg, 0.91 mmol) was heated at 90° C. for 2.5 hours. After cooling, water was added. The precipitate was filtered, washed with water and dried under vacuum. The residue was triturated with ether, filtered, washed with ether and dried under vacuum to give 4-(indol-6-yloxy)-6-methoxy-7-(3-methylsulphonylpropoxy)quinazoline (130 mg, 50%).
