実験手順

(E)-N′-(3-(4-(2-chlorophenyl)-5-(5-(methylsulfonyl)pyridin-2-yl)-4H-1,2,4-triazol-3-yl)acryloyl)-4-cyanobenzohydrazide 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 ambient temperature for 2 h. The final compound was purified by column chromatography (eluting with hexane and ethyl acetate 1:3) to give (E)-4-(5-(2-(4-(2-chlorophenyl)-5-(5-(methylsulfonyl)pyridin-2-yl)-4H-1,2,4-triazol-3-yl)vinyl)-1,3,4-oxadiazol-2-yl)benzonitrile as a yellow solid. Yield: 0.035 g, 12.7%.
