Methyl 5-{[(4-nitrophenoxy)carbonyl]oxy}nicotinate (505 mg) was added to an acetonitrile (10 ml) solution of 2-methyl-6-[4-(2-piperidin-4-ylethyl)piperidin-1-yl]pyridine dihydrochloride (520 mg) and TEA (0.50 ml), followed by stirring at room temperature for 3 hours. The reaction liquid was diluted with EtOAc, washed with an aqueous saturated sodium hydrogencarbonate solution, and dried over anhydrous magnesium sulfate. The solvent was evaporated, and the resulting residue was purified by silica gel column chromatography (eluent: chloroform:methanol=98:2 (v/v)) to obtain methyl 5-{[(4-{2-[1-(6-methylpyridin-2-yl)piperidin-4-yl]ethyl}piperidin-1-yl)carbonyl]oxy}nicotinate (424 mg).
