Abstract: 2mercapto5methoxybenzimidazole,a key intermediate for the synthesis of omeperazole,was synthesized in 80% yield over two steps. Commercially available 2nitro4methoxyaniline was used as starting material and converted via reduction with zinc dust and cyclization with potassium ethyl xanthate into the title compound,suggesting that this procedure is suitable for industrial production.
Key words:2mercapo5methoxybenzimidazole; omeperazole; intermediate; synthesis
