실험 절차

To a mixture of 2-(2-methoxyphenethyl)imino-5,5-dimethyl-1,3-thiazine (0.28 g), triethylamine (0.15 g) and dichloromethane (5 ml) was added dropwise for 3 minutes ethyl chlorothiocarbonate (0.15 g). The mixture was stirred at room temperature for 2 hours. To the solution was added water (30 ml). The mixture was extracted with diethylether (60 ml), dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (n-hexane/ethyl acetate) to give 2-(2-methoxyphenethyl)imino-N-(ethylthiocarbamoyl)-5,5-dimethyl-1,3-thiazine (0.21 g, yield: 60%) as colorless oil.
