Triethylamine → 3-[3-(Thenoylamino)propylthio]pyridine

関与物質

反応手順

To a solution of 2.00 g (8.29 mmol) of 3-(3-aminopropylthio)pyridine dihydrochloride and 4.16 ml (29.9 mmol) of triethylamine in 80 ml of methylene chloride, 1.06 ml (9.95 mmol) of 2-thenoyl chloride was-added under ice-cooling with stirring. The-mixture was stirred at room temperature for 30 minutes. The reaction mixture was washed with a saturated aqueous solution of sodium bicarbonate and water and dried, and then the solvent was distilled off. The residue was purified by column chromatography (eluent: ethyl acetate) to obtain powder. The powder was washed with ether and dried to obtain 1.97 g of the desired compound (yield: 85.3%, yellow powder).
