To a tetrahydrofuran (10 mL)-water (4.0 mL) solution of 4-(4-fluorophenyl)-1,2,3,6-tetrahydropyridine hydrochloride (1.43 g, 6.67 mmol) and sodium carbonate (1.56 g, 14.7 mol), 2,4-dichloro-1,3,5-triazine (1.00 g, 6.67 mmol) was added at 0° C. and the resultant mixture was stirred for 1 hour. After completion of the reaction, ethyl acetate was added to the reaction solution and the resultant mixture was washed with each of saturated ammonium chloride aqueous solution and saturated sodium chloride aqueous solution. The obtained organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (chloroform) to obtain the title compound (1.64 g, yield 85%).
