Reaction Steps

A solution of 6-methoxy-4-(2-methylindol-5-yloxy)-7-(2-(piperidin-4-yloxy)ethoxy)quinazoline (76 mg, 0.17 mmol), (prepared as described in Example 77), in acrylonitrile (0.5 ml), methylene chloride (1 ml) and methanol (1 ml) was stirred overnight at ambient temperature. After removal of the volatiles under vacuum the residue was purified by column chromatography eluting with methylene chloride/methanol (98/2 followed by 95/5 and 90/10). The residue was triturated with ethyl acetate and ether. The resulting solid was filtered and dried under vacuum to give 7-(2-(1-(2-cyanoethyl)piperidin-4-yloxy)ethoxy)-6-methoxy-4-(2-methylindol-5-yloxy)quinazoline (73 mg, 86%).
