실험 절차

A mixture of 7.00 g (33.9 mmol) of ethyl 2-oxo-2,3-dihydrobenzimidazole-1-carboxylate (IV) and 3.02 ml (37.3 mmol) of sulfuryl chloride in acetic acid (90 ml) was stirred at 90° C. for 1 h. The cooled reaction mixture was poured into ice-water. The precipitated solid was filtered off, washed with water, dried in vacuo and recrystallized from ethyl acetate.
