Reaction Steps
4-(Benzyloxy)-2-{[(5-bromopyrimidin-2-yl)oxy]methyl}-3-methylquinoline (1.5 g) was suspended in a mixed solvent (40 mL) of DMF-methanol (1:1), and triethylamine (1 mL) and dichlorobis(triphenylphosphine)palladium(II) (1.2 g) were added thereto, followed by stirring at 100° C. under a carbon monoxide atmosphere (1.0 MPa) for 5 hours. The reaction mixture was allowed to cool to room temperature, and water was added thereto, followed by extraction with ethyl acetate. The organic layer was washed water and saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and then the residue was purified by silica gel column chromatography (eluent: hexane/ethyl acetate=100/0˜50/50). The solvent was evaporated under reduced pressure, and ethyl acetate was added to the residue which was then warmed to be dissolved. Hexane was added to this solution, followed by stirring at room temperature, and the resulting solid was collected by filtration and dried under vacuum at room temperature to obtain 1.034 g of methyl 2-{[4-(benzyloxy)-3-methylquinolin-2-yl]methoxy}pyrimidine-5-carboxylate as a pale yellow solid.
