Synthesis of phenothiazines via smiles rearrangement

Sharma,Gupta, Vandana,Gautam,Gupta

, p. 195 - 198 (2007/10/03)

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.
