Benzylamine → 4-[3-(N-benzylamino)propylthio)pyridine

関与物質

反応手順

In 150 ml of methylene chloride were dissolved 5.22 g (30.8 mmol) of 4-(3-hydroxypropylthio)pyridine and 5.16 ml (37.0 mmol) of triethylamine, methanesulfonyl chloride [2.86 ml (37.0 mmol)] was added, and 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. Then the solvent was distilled off. 2.62 ml (24.0 mmol) of benzylamine was added to the residue, and the mixture was heated at 80° C. for 3 hours. After cooling, the mixture was purified by column chromatography (eluent: chloroform /methanol=25:1) to obtain 1.0 g of the desired compound (yield: 16.1%, yellow oil).
