Abstract
Process for the preparation of 3-hydroxy- and 3-mercapto-1,2,8,9-tetraazaphenylene derivatives, of the formula I, ** (See formula) ** in which X means oxygen or sulfur, as well as their physiologically acceptable addition salts, characterized in that, a compound of the general formula II, ** (See formula) ** in which R2 means hydrogen or a lower alkyl group, one of the radicals A and B means the aldehyde group or one of its respective groups corresponding to the oxidation phase, the other radical meaning the carboxylic acid group or one of its respective groups which correspond to the oxidation phase, wherein the two neighboring carboxylic acid groups can be linked together as anhydride and an aldehydic group and the neighboring carboxylic acid group can, ester bonded together to form a lactone ring, is heated with at least the double molecular dose of hydrazine hydrate and 3-hydroxy-1,2,8,9-tetraazaphenylene is isolated from the reaction solution and, if desired, this compound is treated with an at least equimolar dose of phosphorus pentasulfide until, that the hydroxyl group is replaced by the mercapto group and, if desired, a hydroxylic compound or mercapto thus obtained is transformed, with an acid in organic or organic in an addition salt.
