실험 절차

To a solution of 4-(benzyloxy)-6-bromo-3-methyl-2-{[3-(tetrahydro-2H-pyran-4-ylmethoxy)phenoxy]methyl}quinoline (300 mg) in dioxane (10 mL) were added pyridin-3-yl boric acid (135 mg), tetrakis(triphenylphosphine)palladium(0) (65 mg), and a 1M aqueous sodium carbonate solution (1.60 mL), followed by stirring at 80° C. for 2 hours. The reaction mixture was allowed to cool to room temperature, and water (20 mL) was added thereto, followed by extraction with chloroform (50 mL). The organic layer was washed sequentially with a saturated aqueous sodium hydrogen carbonate solution and saturated brine and then dried over anhydrous magnesium sulfate, and the solvent was evaporated. The residue was purified by silica gel column chromatography (eluent: hexane/ethyl acetate=15/85) to obtain 4-(benzyloxy)-3-methyl-6-(pyridin-3-yl)-2-{[3-(tetrahydro-2H-pyran-4-ylmethoxy)phenoxy]methyl}quinoline (265 mg).
