반응 단계

A solution of 3-chloro-5-nitro-1,2-benzisothiazole (2.00 g) in toluene is treated with iron powder (8.40 g, 325 mesh) and concentrated hydrochloric acid (8 drops), heated to reflux, treated dropwise with water (8.00 mL), refluxed for 35 minutes, cooled to room temperature, and filtered through diatomaceous earth. The resultant filtrate is concentrated in vacuo to obtain a residue. Flash column chromatography of the residue using silica gel and an ethyl acetate/hexanes solution (1:1) gives the title product.
