실험 절차

In 100 ml of methylene chloride were dissolved 11.1 g (100 mmol) of 4-mercaptopyridine and 13.9 ml (100 mmol) of triethylamine, and 9.04 ml (100 mmol) of 3-bromo-1-propanol was added. The mixture was stirred at room temperature for hours. The reaction mixture was washed with a 1N aqueous solution of sodium hydroxide and water and dried. Then the solvent was distilled off. The residue was purified by column chromatography (eluent: ethyl acetate) to obtain 14.2 g of the desired compound (yield: 83.9%, yellow oil).
