실험 절차

To a solution of 2.29g. (0.01 mole) of 2-n-octyl-4-isothiazolin-3-one 1-oxide in 3 ml. of EDC is added 1.2g. (0.01 mole) of sulfuryl chloride in 3 ml. of EDC. The mixture is stirred at room temperature over a weekend. The solution is filtered and concentrated to give an oil. The oil is further purified via column chromatography (100% benzene: silica) to give 1.0g. (33%) of product.
