Reaction Steps

4-Chloro-6,7-dimethoxyquinoline (100 mg), 5-chloro-2-hydroxy-4-methylbenzophenone (443 mg), and 4-dimethylaminopyridine (220 mg) were suspended in o-dichlorobenzene (1 ml), and the mixture was stirred at 140° C. for 7 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 water and was dried over anhydrous sodium sulfate. The solvent was removed therefrom by distillation under the reduced pressure, and the residue was purified by column chromatography using acetone-hexane to give the title compound (175 mg, yield 90%).
