実験手順
After mixing methyl 4-chloro-7-methoxyquinoline-6-carboxylate (WO0050405, P. 34, 8.5 g, 33.77 mmol), 5-hydroxyindole (7 g), diisopropylethylamine (8.9 ml) and N-methylpyrrolidone (8.9 ml), the mixture was heated and stirred at 130° C. for 5 hours and then at 150° C. for 8 hours. After cooling, the solution was adsorbed onto silica gel and purified with a silica gel column (hexane-ethyl acetate system). Ethanol, diethyl ether and hexane were added to the obtained yellow oil, and crystals precipitated upon standing. These were filtered out, washed with diethyl ether and hexane and dried by aspiration to obtain light yellow crystals (3.506 g, 10.06 mmol, 29.80%).
