A facile synthesis of cyanophenothiazines

A one‐pot synthesis of 1, 3 and 4‐cyanophenothiazines and a two‐step approach to 2‐cyanoisomer have been developed. The condensation of 2‐aminobenzenethiol and 2,3 or 3,4‐dihalogenobenzonitriles followed by Smiles rearrangement or by intramolecular aromatic substitution gave the desired ring systmes...
