실험 절차

Triethylamine [12.54 ml (90 mmol)] was added to a suspension of 6.67 g (60 mmol) of 2-mercaptopyridine and 15.24 g (60 mmol) of N-(2-bromoethyl)phthalimide in 200 ml of ethanol and stirred at room temperature for 24 hours. The mixture was heated under reflux for 2 hours. The solvent was distilled off, chloroform was added to the residue, and the mixture was washed with water and dried over anhydrous magnesium sulfate. The solvent was distilled off and the residue was purified by column chromatography (eluent: ethyl acetate/n-hexane=1:2) to obtain 8.00 g of the desired compound (46.9%, colorless crystals).
