Reaction Steps

To a mixture of the crude 2-(1H-benzimidazol-1-yl)-ethanol and 500 g of pyridine, 122 g of acetic anhydride was added dropwise. In a nitrogen atmosphere, the reaction mixture was stirred at 20° C. for 10 hours. The reaction mixture was subjected to conventional aqueous work-up and then purified by vacuum distillation, obtaining 165 g of 2-(1H-benzimidazol-1-yl)ethyl acetate (boiling point 145° C./27 Pa, yield 87%).
