Reaction Steps

5.98 g of (5-hydroxy-1H-benzoimidazol-2-yl)-carbamic acid tert-butyl ester were combinated with 4.67 g of 4-fluorobenzenesulfonyl chloride and 6.75 ml of trietylamine in 100 ml acetone. The reaction mixture was stirred at room temperature for 1 hour. Solvents were evaporated under reduced pressure yielding 6.45 g crude 4-fluoro-benzenesulfonic acid 2-tert-butoxycarbonylamino-1H-benzoimidazol-5-yl ester.
