The structures of 5- and 7-chloro-2-methylbenzothiazole, obtained by the ferricyanide oxidation of m-chlorothioacetanilide were determined by the preparation of the 5-chloro derivative from 2, 5-dichloronitrobenzene through 4-chloro-2-amino-benzenethiol. The two isomers obtained by the ferricyanide oxidation of m-thioacetotoluidide were also structurally determined by the preparation of 2, 5-dimethylbenzothiazole by a similar route as above.
