Reaction Steps
2-Hydroxy-5-methyl-benzaldehyde (344 mg), 4-chloro-6,7-dimethoxyquinoline (113 mg), and 4-dimethylaminopyridine (313 mg) were suspended in o-dichlorobenzene (5 ml), and the suspension was stirred at 160° C. for 2 hr. The reaction solution was cooled to room temperature, and the solvent was removed by distillation under the reduced pressure. Water was then added to the residue, and the mixture was extracted with chloroform. The chloroform layer was washed with aqueous sodium hydroxide solution and saturated brine and was dried over anhydrous magnesium sulfate. The solvent was removed by distillation under the reduced pressure, and the residue was purified by column chromatography using chloroform to give 2-(6,7-dimethoxy-quinolin-4-yloxy)-5-methyl-benzaldehyde (157 mg, yield 96%).
