Reaction Steps
Thieno[3,2-b]pyridin-7-ol (203 mg), 4-chloro-6,7-dimethoxyquinoline (100 mg), and 4-dimethylaminopyridine (110 mg) were suspended in o-dichlorobenzene (6 ml), and the suspension was stirred at 130° 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 ethyl acetate layer was then washed with water and saturated brine and was dried over anhydrous sodium sulfate. The solvent was removed by distillation under the reduced pressure, and the residue was purified by thin layer chromatography using acetone-hexane to give the title compound (4 mg, yield 1%).
