Reaction Steps

6-Hydroxy-7-methoxyquinoline (65 mg), 4-chloro-6,7-dimethoxyquinoline (100 mg), and 4-dimethylaminopyridine (148 mg) were suspended in o-dichlorobenzene (5 ml), and the suspension was stirred at 155° C. overnight. The reaction solution was cooled to room temperature. Water was then added thereto, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with water and was dried over anhydrous sodium sulfate. The solvent was removed by distillation under the reduced pressure, and the residue was purified by column chromatography using acetone-chloroform to give the title compound (134 mg, yield 100%).
