Versuchsvorschrift

A mixture of 6-methoxy-4-(2-methylindol-5-yloxy)-7-(piperidin-4-ylmethoxy)quinazoline (419 mg, 1 mmol), (prepared as described in Example 70), in DMF (6 ml) containing chloroacetonitrile (114 mg, 1.5 mmol), potassium carbonate (346 mg, 2.5 mmol) and potassium iodide (50 mg, 0.3 mmol) was stirred at ambient temperature overnight. The mixture was poured into water and the precipitate was filtered, washed with water and dried under vacuum. The residue was purified by column chromatography, eluting with methylene chloride, followed by methylene chloride/methanol (98/2 and 95/5). After removal of the solvent under vacuum, the residue was triturated with ether, filtered, washed with ether and dried under vacuum to give 7-((1-cyanomethyl)piperidin-4-ylmethoxy)-6-methoxy-4-(2-methylindol-5-yloxy)quinazoline (304 mg, 66%).
