実験手順

4-chloro-N′-[(E)-3-[4-(2-chlorophenyl)-5-(5-methylsulfonyl-2-pyridyl)-1,2,4-triazol-3-yl]prop-2-enoyl]benzohydrazide 10 was dissolved into dichloromethane (10 mL) and triphenyl phosphine (0.27 g, 1.0 mmol), carbon tetrabromide (0.34 g, 1.04 mmol) and triethylamine (0.18 mL, 1.30 mmol) was added. The reaction was kept at room temperature for 2 h. The final compound was purified by column chromatography (eluting with hexane and ethyl acetate 1:3) to give 2-(4-(2-chlorophenyl)-5-((E)-2-(5-(4-chlorophenyl)-1,3,4-oxadiazol-2-yl)vinyl)-4H-1,2,4-triazol-3-yl)-5-(methylsulfonyl)pyridine as a yellow solid. Yield: 0.03 g, 11%.
