4-Chloro-6,7-dimethoxyquinoline (252 mg), 2,3-dihydroxypyridine (396 mg), and 4-dimethylaminopyridine (400 mg) were suspended in o-dichlorobenzene (13 ml), and the suspension was stirred at 160° C. overnight. The reaction solution was cooled to room temperature, the solvent was then removed by distillation under the reduced pressure, and the residue was purified by column chromatography using acetone-chloroform to give 6,7-dimethoxy-4-(2-hydroxy-pyridin-3-yloxy)-quinoline (84 mg, yield 25%).
