4-(2-Iodo-4,5-dimethyl-phenoxy)-6,7-dimethoxyquinoline (compound 164) (95 mg), tri-n-butyl(2-pyridyl)tin (0.25 ml), and tetrakistriphenylphosphine palladium (64 mg) were dissolved in N,N-dimethylformamide (7 ml), lithium chloride (102 mg) was added to the reaction system, and the mixture was stirred at 100° C. for one hr. Water was added to the reaction solution, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was then 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 (3 mg, yield 4%).
