Reaction Steps
Five grams (13.3 mmol) of 5-acetamino-2-(2'-methoxy-4'-methanesulfonyloxy-phenyl)-benzimidazole were suspended in 150 ml of concentrated hydrochloric acid and stirred at 80° C. for two hours. After cooling, the crude product precipitated was subjected to suction filtration and chromatographed on 500 gm of aluminium oxide (neutral) (eluant: methylene chloride with 2.5% ethanol).
