実験手順

A mixture of 6-benzyloxy-4-chloro-7-methoxyquinazoline (0.88 g, 2.9 mmol), (EP1153920 production examples 28-30), 4-fluoro-5-hydroxyindole (0.53 g, 3.5 mmol) and potassium carbonate (0.607 g, 4.39 mmol) in DMF (18 ml) was stirred at 95° C. for 2 hours. After cooling, the mixture was filtered and the volatiles were removed under vacuum. The residue was purified by column chromatography eluting with increasingly polar mixtures of methylene chloride and ethyl acetate to give 6-benzyloxy-4-(4-fluoroindol-5-yloxy)-7-methoxyquinazoline (0.8 g, 67%).
