反応手順
A mixture of 7-{[1-(tert-butoxycarbonyl)piperidin-4-yl]methoxy}-4-chloro-6-methoxyquinazoline (4.6 g), 5-hydroxy-3-methylindole (2 g), (Journal of Organic Chemistry 1993, 58, 3757), potassium carbonate (3.1 g) and DMF (20 ml) was stirred and heated to 90° C. for 2 hours. The solid was removed by filtration washed with acetonitrile and the combined filtrates concentrated to dryness under vacuum. The product so obtained was triturated under ether/petroleum ether (8/2), collected by filtration and dried to give 7-{[1-(tert-butoxycarbonyl)piperidin-4-yl]methoxy}-6-methoxy-4-[(3-methyl-1H-indol-5-yl)oxy]quinazoline (5.8 g).
