3 hợp chất 5-bromo-N’-(1-arylethylidene)-2-hydroxybenzohydrazide đã

được tổng hợp từ nguyên liệu ban đầu là acid 2-hydroxybenzoic (acid salicylic). Khi

đun hồi lưu 3 hydrazide ở trên với anhydride acetic đã tạo ra 3 hợp chất mới 2-(4-

acetyl- 5-aryl-5-methyl-4,5-dihydro-1,3,4-oxadiazol-2-yl)-4-bromophenyl acetate. Cấu

trúc của các hợp chất này đã được khẳng định bằng phổ hồng ngoại, 1 H-NMR, 13 CNMR và HR-MS.
