Process for the preparation of new heterocyclic compounds characterized in that the halide of isonicotinic acid is condensed with the hydrazide of isonicotinic acid being one of the two pyridine nuclei substituted in position-2 and/or in position-6 by a halogen or by a possibly substituted hydroxy mercapto or amino group and that in the case where chlorine is substituted in position-2 and/or position-6 the chlorine is replaced in the condensation product obtained, if appropriate, by another of the mentioned substituents and in the case where two chlorine atoms are present, one of these atoms is replaced, if appropriate, by hydrogen.
