Triethylamine → 4-[3-(2-Thenoylamino)propyloxy]pyridine

Participants

Reaction Steps

To a solution of 700 mg (4.60 mmol) of 4-(3-aminopropyloxy)pyridine and 0.77 ml (5.52 mmol) of triethylamine in 30 ml of methylene chloride, 0.50 ml (4.68 mmol) of thenoyl chloride 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 the solvent was distilled off. The residue was purified by column chromatography (eluent: ethyl acetate) to obtain 850 mg of the desired compound (yield: 70.0%, colorless crystals).
