실험 절차

One gram (2.91 mmol) of 5-cyano-2-(2'-methoxy-4'-methanesulfonyloxy-phenyl)-benzimidazole was added batchwise to 15 ml of concentrated sulfuric acid, and the resulting mixture was stirred for 24 hours at ambient temperature. The solution was then poured onto 300 ml of ice water, and the product precipitated was subjected to suction filtration and recrystallized from methanol.
