Reaction Steps
Methyl 4-[2-(3-cyanobenzoyl)hydrazino]benzoate (0.59 g, 2.0 mmol) and carbonyldiimidazole (0.49 g, 3.0 mmol) are stirred at 80° C. in dichloroethane (20 mL) overnight, and the mixture is then subjected to chromatography directly (silica gel, 1:9 ethyl acetate-dichloromethane) to provide methyl 4-[5-(3-cyanophenyl)-2-oxo-1,3,4-oxadiazol-3(2H)-yl]benzoate (0.63 g, 98%). MS (ES+) m/z: 322.
