  The present invention relates to a process for preparing 2-(2-pyridylmethyl)sulphinyl-1H-benzimidazoles that are proton pump inhibitors, using as intermediates 2-benzimidazolyl-sulphinic acid derivatives. The present invention also relates to the intermediate compounds, their use and a process for the preparation thereof. These novel intermediate compounds are 2-benzimidazolylsulphinicacid esters that are obtained from their corresponding alkaline salts, which are in turn obtained by oxidation of substituted 2-mercaptobenzimidazoles. The intermediate compounds of the invention are converted into 2-(2-pyridylmethyl)sulphinyl-1H-benzimidazoles by reaction with substituted 2-methylpyridines.

  本发明涉及一种制备质子泵抑制剂2-(2-吡啶甲基)亚磺酰基-1H-苯并咪唑的方法，其中使用2-苯并咪唑基-亚磺酸衍生物作为中间体。本发明还涉及中间体化合物、其用途和制备方法。这些新型中间体化合物是2-苯并咪唑基-亚磺酸酯，通过其对应的碱性盐的氧化得到。本发明的中间体化合物通过与取代的2-甲基吡啶反应转化为2-(2-吡啶甲基)亚磺酰基-1H-苯并咪唑。

  [FR] L'invention porte sur un procédé de préparation de 2-(2-pyridylméthyl) sulphinyl-1H-benzimidazoles, inhibiteurs de la pompe à protons, utilisant comme intermédiaires des dérivées de l'acide 2-benzimidazolylsulphinique. L'invention porte également sur lesdits intermédiaires, leur utilisation et leur procédé de préparation. Ces nouveaux composés intermédiaires sont des esters de l'acide 2-benzimidazolylsulphinique, obtenus de leur sels alcalins correspondants, obtenus à leur tour par oxydation de 2-mercaptobenzimidazoles. Lesdits intermédiaires sont convertis en 2-(2- pyridylméthyl)sulphinyl-1H-benzimidazoles par réaction avec des 2- méthylpyridines substituées.
