Production of 2-(2-pyridylmethylsulfinyl) benzimidazole compounds by selective oxidation in the presence of a vanadium catalyst

摘要

2-(2-pyridylmethylsulfinyl)benzimidazole compounds are produced by subjecting 2-(2-pyridylmethylthio)benzimidazole compounds to oxidation with hydrogen peroxide in the presence of vanadium compounds in good yield and with low production of by-products.
