This research include synthesis of some new Bis-1,2,3-triazole from the reaction of an aryl azides and propargylic phenyl ethers. The propargylic ether was prepared from resorcinol by its reaction with propargyl bromide , while an aryl azides were result from treatment of diazoniume salts of an aniline derivatives with sodium azide. The triazole derivatives finally synthesized from the reaction of an figazide derivatives with acetylenic ether via Cu(I) click chemistry . The compounds were identified by FTIR, 1H NMR and 13C NMR. The biological activity of synthesized derivatives was examined against urease enzyme. the result was found that Tr2 ,Tr3compounds inhibit the activity of the urease to hydrolyse urea into CO2 and NH3,while Tr1 do not show any effect .
