Abstract
Process for the manufacture of heterocyclic hydrazine derivatives, which comprises condensing an acid of the general formula R1-COOH in which represents a radical of hydrazine that can carry 1 to 3 substituents of halogen, alkyl, alkoxy or alkylmercapto with a substituted hydrazine of general formula H2N-NH-R2 wherein R 2 represents an aralkyl radical, an alicyclic hydrocarbon radical having not more than 7 carbon atoms or a saturated aliphatic hydrocarbon radical having not more than 7 carbon atoms in the presence of a N, N'-disubstituted carbodiimide and, if desired, converting the condensation product into a salt.
