실험 절차

4-Chloro-6-methoxy-7-((1-methylpiperidin-4-yl)methoxy)quinazoline (200 mg, 0.62 mmol), (prepared as described for the starting material in Example 10), was suspended in DMF (3 ml) under argon. 3-Cyano-7-hydroxyquinoline (116 mg, 0.68 mmol) and potassium carbonate (129 mg, 0.93 mmol) were added and the reaction mixture was heated at 95° C. for 90 minutes. Upon cooling to ambient temperature the mixture was diluted with dichloromethane and poured on the top of an ISOLUTE silica column. Elution was done using successively dichloromethane, dichloromethane/methanol (95/5) and dichloromethane/methanol saturated with ammonia (95/5). Evaporation of the solvent and trituration of the solid in ether gave 4-(3-cyanoquinolin-7-yloxy)-6-methoxy-7-((1-methylpiperidin-4-yl)methoxy)quinazoline (244 mg, 86%).
