Alkylation of 5-aryl-1,3,4-oxadiazole-2-thiones with alkyl halides was carried out, where instead of the expected 2-alkylthio-5-aryl-1,3,4-oxadiazoles obtained N'-((alkylsulfanyl) carbonyl)benzohydrazides having a linear structure without an oxadiazole ring. By slow evaporation of solvents at room temperature were obtained crystals of N’-((ethylsulfanyl)carbonyl)-2-oxymethylbenzohydrazide 7 from ethanol, N’-((prophylsulfanyl)carbonyl)benzohydrazide 8 from ethanol, N’-((pentylsulfanyl) carbonyl)benzohydrazide 9 from methanol:chloroform and N’-((hexylsulfanyl)carbonyl)benzohydrazide 10 from acetonitrile.
