Synthesis of 3-bromo/1,2-dimethylphenothiazines is reported by Smiles rearrangement of 5-bromo/3,4-dimethyl-2-formamido-2′-nitrodiphenylsulfides. The later were obtained by the formylation of 2-amino-5-bromo/ 3,4-dimethyl-2′-nitrodiphenylsulfides which were prepared by the condensation of 2-amino-5-bromo/3,4-dimethylbenzenethiols with ?-halonitrobenzenes.
