| titleOfInvention | Process for producing 3-halo-1,2-benzisothiazoles |
| abstract | General formula (1): ## STR1 ## wherein R 1 is a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, an alkoxycarbonyl group having 2 to 5 carbon atoms, or a nitro group. Or a halogen atom), a 1,2-benzisothiazol-3-one represented by the general formula (2), wherein thionyl halide is reacted in a polar solvent: A process for producing 3-halo-1,2-benzisothiazoles represented by the formula: wherein R1 is the same group as R1 in the general formula (1) and X is a halogen atom. The 3-halo-1,2-benzisothiazoles obtained by the method of the present invention are suitably used as a raw material for producing pharmaceuticals. |
