2-Oxo-1-[[2-(3,4,5-trimethoxyphenyl)pyridin-4-yl]methyl]piperazine (62 mg) was dissolved in acetonitrile (5 mL), and to the solution potassium carbonate (24 mg), potassium iodide (29 mg) and 4-chloromethyl-2-(3,4,5-trimethoxyphenyl)pyridine (51 mg) were added, and the mixture was stirred at 80° C. for 1 hour. The reaction mixture was concentrated under reduced pressure, ethyl acetate was added to the residue, and the resultant mixture was washed with a saturated aqueous solution of sodium hydrogencarbonate, water and saturated brine, dried over anhydrous sodium sulfate and concentrated under reduced pressure. The resultant oil was purified by preparative TLC on silica gel (chloroform:methanol=25:1) to obtain the title compound as a hydrochloride.
