A Facile Synthesis of Cyanophenothiazines

Marivingt-Mounir, Cecile,Mettey, Yvette,Vierfond, Jean-Michel

, p. 843 - 845 (1998)

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.
