实验步骤: A solution of 3-chloro-2-pyridylacetonitrile [prepared by the method described in JP08295663] (1.46 g, 9.57 mmol) in DMSO (19 mL) was slowly added to NaH (60% oil dispersion, 1.01 g, 25.3 mmol), and the mixture was stirred at room temperature for 1 h. A solution of N,N-bis(2-chloroethyl)-p-methoxybenzylamine (2.21 g, 8.43 mmol) in DMSO (19 mL) was added, and the resulting mixture was stirred at 75° C. for 4 h. After cooling, water (100 mL) was added, and the mixture was extracted with ethyl acetate. The organic extract was washed with brine, dried (Na2SO4), and the solvent was removed under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=3/2) to give 4-(3-chloro-2-pyridyl)-4-cyano-1-(4-methoxyphenyl)methylpiperidine 1 (1.91 g, 60%) as an orange oil. the resulting mixture was stirred at 75° C. for 4 h After cooling the mixture was extracted with ethyl acetate The organic extract was washed with brine dried (Na2SO4) the solvent was removed under reduced pressure The residue was purified by silica gel column chromatography (hexane/ethyl acetate=3/2)
