실험 절차

4-[(2-Iodo-6-methyl-3-pyridyl)oxy]-6,7-dimethoxyquinoline (compound 116) (84 mg), 2,6-dichlorophenylboronic acid (191 mg), and tetrakistriphenylphosphine palladium (12 mg) were dissolved in toluene (1 ml) to prepare a solution. A saturated aqueous sodium hydrogencarbonate solution (1 ml) was added to the solution, and the mixture was stirred at 80° C. for 3 hr. The reaction solution was filtered, the solvent was then removed by distillation under the reduced pressure, and the residue was purified by column chromatography using methanol-chloroform to give the title compound (79 mg, yield 90%).
