Procedure

A mixture of 6-methoxy-4-(2-methylindol-5-yloxy)-7-(piperidin-4-ylmethoxy)quinazoline (600 mg, 1.43 mmol), (prepared as described in Example 70), 1-(2-chloroethyl)-pyrrolidine (292 mg, 1.72 mmol) in methanol (14 ml) containing sodium carbonate (262 mg, 4.3 mmol) and potassium iodide (48 mg, 0.29 mmol) was heated at 50° C. for 20 hours. After cooling, the volatiles were removed under vacuum. The residue was purified by preparation HPLC on reverse C18 silica eluting with methanol/aqueous ammonium carbonate (2g ammonium carbonate per liter saturated with CO2) (60/40 followed by 70/30). The fractions containing the expected product were combined and the volatiles were removed under vacuum. The residue was triturated with ether and the solid was filtered, washed with ether and dried under vacuum to give 6-methoxy-4-(2-methylindol-5-yloxy)-7-(1-(2-(pyrrolidin-1-yl)ethyl)-piperidin-4-ylmethoxy)quinazoline (102 mg, 20%).
