Reaktionsschritte

2-Iodo-4,5-dimethylphenol (447 mg), 4-chloro-6,7-dimethoxyquinoline (466 mg), and 4-dimethylaminopyridine (539 mg) were suspended in o-dichlorobenzene (20 ml), and the mixture was stirred at 130° C. for 4 hr. The reaction solution was cooled to room temperature, and the solvent was then 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 by distillation under the reduced pressure. The residue was purified by column chromatography using acetone-chloroform to give the title compound (452 mg, yield 50%).
