Name is 3-Chlorobenzo[d]isothiazole, as a common heterocyclic compound, it belongs to isothiazole compound, and cas is 7716-66-7, its synthesis route is as follows.,7716-66-7
a) A mixture of 32 parts of ethyl 1-piperazinecarboxylate, 17 parts of 3-chloro-1,2-benzisothiazole and 45 parts of N , N -dimethylacetamide was stirred for 0.5 hour at 150¡ãC. After cooling to 50¡ãC, the reaction mixture was poured into ice water. The aqueous layer was decanted and the oily layer was stirred again in water. The product from the oily layer was extracted with trichloromethane. The extract was dried, filtered and evaporated. The residue was purified by column chromatography over silica gel using a mixture of trichloromethane and methanol (95:5 by volume) as eluent. The pure fractions were collected and the eluent was evaporated, yielding 13 parts (44percent) of ethyl 4-(1,2-benzisothiazol-3-yl)-1-piperazinecarboxylate as a residue (interm. 12).
With the complex challenges of chemical substances, we look forward to future research findings about 3-Chlorobenzo[d]isothiazole
