1-methyl-6-[5-(2-pyridin-3-ylethylamino)pentyloxy]-1H-quinolin-2-one (182 mg), 2-bromopyridine (0.060 ml), palladium acetate (II) (11.2 mg), xantphos (32 mg), and sodium t-butoxide (68 mg) were added to toluene (2 ml). The mixture was heated at 80° C. for 10 hours under nitrogen atmosphere. The reaction liquid was cooled to room temperature. Water was added to the reaction mixture, followed by extraction with dichloromethane. The organic layer was dried over anhydrous sodium sulfate. The filtrate was condensed under reduced pressure, and the residue was purified by silica gel column chromatography (ethyl acetate). The purified product was condensed under reduced pressure. A 1N-hydrogen chloride in ethanol solution (0.58 ml) was added to a ethanol solution (5 ml) of the residue, and the liquid was stirred at room temperature, and concentrated under reduced pressure. Ethanol and diethyl ether were added to the residue. The precipitated insoluble matter was separated, washed with diethyl ether, and dried to give the title compound (72 mg) as a yellow powder.
