    摘要: The present invention relates to a process for preparing valsartan from a compound of general formula (I), wherein R is cumyl, trityl or t-butyl. The process comprises a first step, wherein the protective group is eliminated and thereafter the oxazolidinone ring is opened by catalytic hydrogenationin the presence of an organic base. Finally, Valsartanor a pharmaceutically acceptable salt thereofis isolated.

    摘要: The present invention relates to a process for preparing2-(2- pyridylmethyl)sulphinyl-1H-benzimidazoles that are proton pump inhibitors, using as intermediates 2-benzimidazolylsulphinic acid derivatives. The present invention also relates to saidintermediate 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 substituted2- methylpyridines.
