Reaction Steps

3-Iodobenzohydrazide (1.00 g, 3.82 mmol) obtained in Step 1 of Example 52 was dissolved in THF (19 mL), and the mixture was stirred at room temperature for 1 hour after adding 1,1′-carbonyldiimidazole (681 mg, 4.18 mmol). The mixture was stirred after adding 6 mol/L hydrochloric acid (20 mL) and water (20 mL), and the precipitated solid was filtered off and dried to give 5-(3-iodophenyl)-1,3,4-oxadiazol-2(3H)-one (779 mg, 71%).
