実験手順

To a solution of 700 mg (4.60 mmol) of 4-(3-aminopropyloxy)pyridine and 1.54 ml (11.0 mmol) of triethylamine in 30 ml of methylene chloride, 830 mg (4.66 mmol) of nicotinoyl chloride hydrochloride was added under ice-cooling with stirring. The mixture was stirred at room temperature for 1.5 hours. The reaction mixture was washed successively with a saturated aqueous solution of sodium bicarbonate and brine and dried over anhydrous magnesium sulfate, and then the solvent was distilled off. The residue was purified by column chromatography (eluent: ethanol/ethyl acetate=1:10 to 1:5) to obtain 1.05 g of the desired compound (yield: 85.8%, colorless crystals).
