YieldReaction ConditionsOperation in experiment
With potassium carbonate; In pyridine; ethanol; Example 5 3-hydroxy-5-[(5-nitrothiazol-2-yl)mercapto]-4-phenyl-1,2,4-triazole (Compound 5) The title compound was prepared by the general method described by Potts, K.T.(1961) Chem. Rev. 61:87. 4-Phenyl-3-thiosemicarbazide (4.18 g) (Aldrich) was dissolved in 50 mL of pyridine and treated with 2.71 g of ethyl chloroformate at 0° C. The reaction was stirred for 2 hours and then refluxed for 18 hours. Evaporation of the solvent and trituration with water gave 2.5 g of 3-hydroxy-5-mercapto-4-phenyl-1,2,4-triazole. 3-Hydroxy-5-mercapto-4-phenyl-1,2,4-triazole (1.93 g) was stirred in 10 mL of ethanol with 1.1 equivalent of potassium carbonate in 10 mL ethanol for one hour and then reacted with 2.09 g of <strong>[3034-48-8]<strong>[3034-48-8]2-bromo-5-nitrothiazol</strong>e</strong> as in Example 1. Crystallization from ethanol and water gave 0.6 g of 3-hydroxy-5-[(5-nitrothiazol-2-yl)mercapto]-4-phenyl-1,2,4-triazole, a dark yellow solid, M.P. 188-190° C.

80% In methanol; for 3h;Reflux; The ligand was prepared by the following method. A solution of <strong>[2631-77-8]3,5-diodosalicylaldehyde</strong> (1 mmol, 0.4 g) in methanol (15 ml) was added dropwise to a solution of 4-phenylthiosemicarbazide (1 mmol, 0.17 g) in methanol (15 ml) with stirring at reflux. After being stirred for 3 h, the resulting white solids were removed by filtration, washed with cold ethanol and dried in vacuo over anhydrous CaCl2. M.p: 192 C, Yield: 80%.
