Reaction Steps
4-Chloro-6,7-dimethoxyquinoline (240 mg), 3-hydroxy-2-methyl-quinoline-4-carboxylic acid (232 mg), and 4-dimethylaminopyridine (372 mg) were dissolved in o-dichlorobenzene (10 ml) to prepare a solution which was stirred at 160° C. overnight. The reaction solution was cooled to room temperature, water was then added to the reaction solution, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was then 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 (37 mg, yield 11%).
