Abstract

N1-Phenyl- and N1-(3,5-dichloro-2-pyridyl)amidrazones have been synthesized by the reaction of imino esters of heterocyclic acids with phenyl- or (3,5-dichloro-2-pyridyl)hydrazine. Acylation of the products with acid chlorides leads to 1-phenyl- and 1-(3,5-dichloro-2-pyridyl)-3-hetaryl-5-R2-1H-1,2,4-triazoles. Compounds of this type are also formed by the condensation of N-acylimino esters of heterocyclic acids with phenyl- or (3,5-dichloro-2-pyridyl)hydrazine.
