Zusammenfassung:The present invention relates to a process for the preparation of products of formula (1):in which R denotes H or an alkyl group containing from 1 to 10 carbon atoms, it being possible for this alkyl group to be substituted by one or more aryl, heteroaryl, hydroxyl or alkenyl groups, in which process hydrazine is reacted with a deficiency of carboxylic acid RCOOH and then the water of reaction and optionally the water of dilution of the hydrazine and of the acid is removed.It is particularly useful for preparing 4-amino-1,2,4-triazole.
