Nine new aryloxyacetyl thioureas were synthesized by the reaction of 5-(p-bromo-phenoxymethyl)-2-amino-1,3,4-thiodiazole with aryloxyacetyl isothiocyanates and the structures were confinned by I H NMR, IR and elemental analysis. The biological activity tests at room temperature showed that some of the title compounds exhibited bet...
