Reaction Steps
4-Chloro-6,7-dimethoxyquinoline (330 mg), 3-hydroxy-6-methyl-2-pyridinecarbaldehyde (200 mg), and 4-dimethylaminopyridine (360 mg) were suspended in o-dichlorobenzene (7 ml), and the suspension was stirred at 150° C. for 3 hr. The reaction solution was cooled to room temperature and was then purified by column chromatography using acetone-chloroform to give 3-[6,7-dimethoxy-4-quinolyl]oxy}-6-methyl-2-pyridinecarbaldehyde (24 mg, yield 5%).
