Abstract
Process for the preparation of new 1,2,8,9-tetraazaphenalenes of the general formula I, ** (See formula) ** in which R1 means hydrogen or a lower alkyl group with up to 6 carbon atoms, R2 means hydrogen, a halogen atom, a hydroxy group or a lower alkoxy group with up to 6 carbon atoms, or the carboxylic group, and its addition salts and physiologically tolerable quaternary ammonium compounds, characterized in that a compound of the general formula II ** (See formula) ** in which R2 has the significance indicated above and A each means a group of aldehyde, or a group corresponding to the oxidation phase, which may be linked to the carboxyl group to a lactone ring, is heated with at least two times the equimolecular dose of hydrazine hydrate until ring closure is effected, the originating compound is isolated and if desired is transformed with an organic inorganic acid into an addition salt or transformed with a lower alkylating agent, in the form of if known, in a quaternary ammonium compound.
