Reaction Steps

3-Iodo-N′-propionylbenzohydrazide (382 mg, 1.20 mmol) obtained in Step 2 was dissolved in acetonitrile (21 mL), and the mixture was stirred at 60° C. for 2 hours after adding triphenylphosphine (629 mg, 2.40 mmol), carbon tetrachloride (0.46 mL, 4.80 mmol), and triethylamine (0.33 mL, 1.54 mmol). After concentrating the mixture under reduced pressure, the residue was purified by silica gel column chromatography to give 2-ethyl-5-(3-iodophenyl)-1,3,4-oxadiazole (331 mg, 92%).
