Reaction Steps

A solution of 4-chloro-6-methoxy-7-((1-cyanomethylpiperidin-4-yl)methoxy)quinazoline (200 mg, 0.58 mmol) and 5-hydroxyindole (85 mg, 0.63 mmol) in DMF (3 ml) containing cesium carbonate (282 mg, 0.86 mmol) was stirred at 90° C. for 90 minutes. After cooling, the mixture was poured onto water (25 ml). The precipitate was filtered, dried under vacuum and purified by reverse phase column chromatography on silica (Kromasil® C18) eluting with methanol/water (1% acetic acid) (1/1). The fractions containing the expected product were combined and evaporated to give 7-((1-cyanomethyl)piperidin-4-ylmethoxy)-4-(indol-5-yloxy)-6-methoxyquinazoline (44 mg, 17%).
