Reaction Steps
2-(2,4-Difluoro-phenyl)-quinolin-3-ol (220 mg), 4-chloro-6,7-dimethoxyquinoline (237 mg), and 4-dimethylaminopyridine (380 mg) were suspended in o-dichlorobenzene (10 ml), and the suspension was stirred at 145° C. for 8 hr. 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 organic layer was washed with water and was dried over anhydrous sodium sulfate. The solvent was removed by distillation under the reduced pressure. The residue was purified by thin layer chromatography using acetone-chloroform to give the title compound (104 mg, yield 27%).
