Reaction Steps

4-Chloro-6,7-dimethoxyquinoline (106 mg), 2,3-dihydroxyquinoline (50 mg), and 4-dimethylaminopyridine (124 mg) were suspended in o-dichlorobenzene (5 ml), and the suspension was stirred at 150° C. for 8 hr. The reaction solution was cooled to room temperature, water was then added thereto, and the mixture was extracted with ethyl acetate. The organic 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 methanol-chloroform to give 6,7-dimethoxy-4-(2-hydroxy-quinolin-3-yloxy)-quinoline (40 mg, yield 37%).
