Reaction Steps
A mixture of ethyl α,α-dimethyl-5-nitro-1,2-benzisothiazole-3-acetate (0.714 g, 2.42 mmol), iron powder (0.500 g), 10% acetic acid (23.0 mL) and ethyl acetate (23.0 mL) is stirred at 54-58° C. for one hour, cooled, and poured into saturated sodium hydrogen carbonate solution. The resultant aqueous mixture is extracted with ethyl acetate. The combined organic extracts are washed sequentially with water and brine, dried over anhydrous sodium sulfate, and concentrated in vacuo to obtain a yellow oil. Column chromatography of the oil using silica gel and a 10% ethyl acetate in methylene chloride solution gives the title product as a light brown oil which is identified by NMR spectral analysis.
