실험 절차

In 120 ml of methylene chloride was dissolved 5.60 g (33.1 mmol) of 4-(3-hydroxypropylthio)pyridine and 5.53 ml (39.7 mmol) of triethylamine. 3.07 ml (39.7 mmol) of methanesulfonyl chloride 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, and then the solvent was distilled off, 5.34 g (28.8 mmol) of dodecylamine was added to 7.12.g of 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 2.86 g of the desired compound (yield: 29.5%, yellow oil).
