反応手順

To a solution of 2-chloro-5-(chloromethyl)pyridine (500 mg, 3.08 mmole) in 8 mL of dry acetonitrile is 384 mg (3.39 mmol) of N-methylcyclohexylamine followed by 468 mg (3.39 mmol) of potassium carbonate. The reaction is heated at 80° C. for 20 h. After cooling, the reaction mixture is quenched with 5 mL of water, extracted three-times with methylene chloride, and dried over sodium sulfate. Concentration of the solvent provided an oil which was purified by silica gel chromatography to provide 700 mg (95% yield) of (6-Chloro-pyridin-3-ylmethyl)-cyclohexyl-methyl-amine. C13 NMR 26.1, 26.6, 28.9, 37.7, 54.5, 62.8, 124.1, 135.1, 139.5, 149.9; MS 239.3 (M+H).
