Abstract
Procedure for the preparation of fentiazines and their compounds characterized by heating in an anhydrous solvent medium in the presence of an acid fixing agent, a diphenyl sulfide ortho substituted in a ring by the group -NHZ in which Z represents hydrogen or a group aminoalkylamino (in which the terminal nitrogen atom is tertiary) and in the other ring by a halogen atom remaining without substituting all the remaining positions or being substituted by at least one of the remaining positions (preferably ortho or para) by an atom halogen or by a lower alkyl alkoxy or phenoxy group.
