Reaction Steps

2-p-Toluyl-[1,8]naphthyridin-3-ol (2 mg), 4-chloro-6,7-dimethoxyquinoline (6 mg), and 4-dimethylaminopyridine (3 mg) were suspended in o-dichlorobenzene (1 ml), and the suspension was stirred at 130° C. for 14.5 hr. The reaction solution was cooled to room temperature, water was then added to the reaction solution, and the mixture was extracted with chloroform. The chloroform layer was then washed with water and saturated brine and was dried over anhydrous magnesium sulfate. The solvent was removed by distillation under the reduced pressure, and the residue was purified by column chromatography using chloroform-methanol to give the title compound (0.7 mg, yield 20%).
