Abstract
Process for the preparation of heterocyclic compounds characterized in that a pyridine-4-carboxylic acid compound of the general formula ** is transformed in which x represents an amino or an alkoxyl hydroxyl radical or an halogen y or y 'represent a halogen hydrogen atom or an alkoxy or acylamino moiety with a substituted non-isocyclic hydrazine derivative in the nucleus or a salt of this derivative than in the case where y and y' represent a nitrogen atom it does not contain any grouping of atom formed with one of the two azoe atoms of the hydrazine, a saturated N-heterocycle of 6 elements, the y and y 'substituents possibly also being transformed according to the methods known per se.
