The acylhydrazone compound named ethyl N'-furan-2-carbonylbenzohydrazonate was synthesized by the condensation of ethyl benzimidate hydrochloride with furan-2-carbohydrazide. The treatment of the acylhydrazone with hydrazine hydrate afforded 4-amino-3-furan-2-yl-5-phenyl-1,2,4-triazole. The usage of this compound with various aromatic aldehydes resulted in the formation of 4-arylidenamino-3-furan-2-yl-5-phenyl-1,2,4-triazoles. Sodium borohydride reduction of 4-arylidenamino derivatives afforded 4-alkylamino-3-furan-2-yl-5-phenyl-1,2,4-triazoles. The obtained products were identified by FT-IR, H-1-NMR, C-13-NMR. A series of compounds were evaluated for their antibacterial, antiurease, and antioxidant activities. The results showed that the synthesized new compounds had effective antiurease and antioxidant activities.
