Reaction Steps

To a solution of 3-[4-(methylthio)phenyl]-1-benzofuran-5-carbohydrazide (0.25 g, 0.83 mmol) and triethylamine (0.17 mL, 1.25 mmol) in N,N-dimethylformamide (5 mL) was added N,N′-carbonyldiimidazole (0.27 g, 1.68 mmol) at 0° C., and the resulting mixture was stirred for 1 hr. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate/tetrahydrofuran. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was recrystallized from hexane/ethyl acetate to give the title compound (0.20 g, yield 74%) as colorless crystals.
