Reaction Steps

N′-[(E)-3-[4-(2-chloro-4-trifluoromethoxyphenyl)-5-(5-methylsulfonyl-2-pyridyl)-1,2,4-triazol-3-yl]prop-2-enoyl]-2-methoxy-pyridine-4-carbohydrazide was dissolved into dichloromethane (10 mL), and triphenylphosphine (0.19 g, 0.736 mmol), carbon tetrabromide (0.24 g, 0.736 mmol) and triethylamine (0.18 mL, 1.30 mmol) was added. The reaction mixture was kept at ambient 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-chloro-4-trifluoromethoxyphenyl)-5-((E)-2-(5-(2-methoxypyridin-4-yl)-1,3,4-oxadiazol-2-yl)vinyl)-4H-1,2,4-triazol-3-yl)-5-(methylsulfonyl)pyridine as a yellow solid. Yield: 0.07 g, 30%.
