Reaction Steps

To a solution of 4-(benzyloxy)-6-bromo-3-methyl-2-{[3-(tetrahydro-2H-pyran-4-ylmethoxy)phenoxy]methyl}quinoline (400 mg) in dioxane (10 mL) were added piperidin-2-one (90 mg), tris(dibenzylideneacetone)dipalladium(0) (35 mg), cesium carbonate (360 mg), and (9,9-dimethyl-9H-xanthen-4,5-diyl)bis(diphenylphosphine) (65 mg), and the mixture was stirred at 100° C. for 30 hours. The reaction mixture was allowed to cool to room temperature and then concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: chloroform/methanol=97/3) to obtain 1-[4-(benzyloxy)-3-methyl-2-{[3-(tetrahydro-2H-pyran-4-ylmethoxy)phenoxy]methyl}quinolin-6-yl]piperidin-2-one (328 mg).
