Four new compounds N-(4-nitrophenyl)-N’-(isobutoxycarbonyl) thiocarbamide (1), N-(2, 4-nitrophenyl)-N’-(isobutoxycarbonyl) thiocarbamide (2), N-(4-nitrophenyl)-N’-(ethoxycarbonyl) thiocarbamide (3) and N-(2-Chloro- 4-nitrophenyl)-N’-(ethoxycarbonyl) thiocarbamide (4) were prepared and their structures confirmed by using various spectroscopic (FT-IR, UV–Visible, 1H and 13C NMR) and single crystal X-ray studies of 1 and 3. The presence of intramolecular (N–H?O[dbnd]C) hydrogen bond in the crystal structure of both the compounds causes planarity of carbonyl thiocarbamide unit and trans orientation of C[dbnd]O and C[dbnd]S group. The intermolecular contacts (C–H?S, C–H?O and N–H?S) present in crystal structures have been examined by Hirshfeld surface analysis and their associated 2D fingerprint plots. All the compounds were assessed for their in vitro cytotoxic properties against a panel of seven human cancer cells such as cervical carcinoma (2008, C13*), colorectal (HT29 and HCT116) and ovarian carcinoma (A2780, A2780/CP and IGROV-1). Among them, compounds 2 and 4 exhibited better activity than 1 and 3 against all the cell lines tested.

Paragraph 0059; 0061, (2018/12/05)
The invention discloses a synthetic method of a 1,3,4-thiadiazole derivative. The method comprises the following steps: (1) using hydrazine hydrate as a raw material, under the action of a catalyst, reacting with acid, to obtain a hydrazide compound I; (2) using alkyl chloroformate and thiocyanate to react in a condition of a solvent, to obtain an isothiocyanate compound II; (3) in a reaction system of the isothiocyanate compound II, adding solution containing the compound I, reacting to obtain solution containing a compound III; (4) processing the solution of the compound III by dehydrating,neutralizing, and washing, to obtain a compound IV; (5) in the conditions of an acid-binding agent and a solvent, adding alkyl halide or sulfuric acid diester into the compound IV, reacting to obtaina compound V; and (6) enabling the compound V to perform an amination reaction with primary amine, to obtain the 1,3,4-thiadiazole derivative VI. The preparation method has the advantages of green andno pollution, simple and convenient operation, higher yield, mild reaction condition and the like.
