Abstract
In order to find biologically active urea compounds,seven new N-[5-(3-pyridyl)-1,3,4-thiadiazol-2-yl]-N'-(substituted phenyl)urea derivatives were synthesized by the reaction of 2-amino-5-(3-pyridyl)-1,3,4-thiadiazole with aroylazides,which were prepared starting from carboxylic acids,ethyl chloroformate and sodium azide by one-pot procedure.Their structures were confirmed by IR,1H NMR spectroscopy and elementary analysis.The preliminary biological activity tests showed that some of the title compounds have good plant-growth regulating activity.
