[EN] A PROCESS FOR THE PREPARATION OF PANTOPRAZOLE AND INTERMEDIATES THEREFOR [FR] PROCEDE DE PREPARATION DE PANTOPRAZOLE ET DE PRODUITS INTERMEDIAIRES DE CELUI-CI
A process for the oxidation of thioethers to sulfoxides or sulfones or for the oxidation of sulfoxides to sulfones by treatment of thioethers or sulfoxides with an oxidizing amount of &egr;-phthalimidoperhexanoic acid is particularly useful for the preparation of compounds of industrial interest, in particular pharmaceuticals for human or veterinary use.

A process for the preparation of pantoprazole and the salts thereof, comprising the reaction of a mercaptoimidazole with a picoline, to give a 2-pyridinyl-methylsulfinyl-2-benzimidazole intermediate, the oxidation thereof with ε-phthalimidoperhexanoic acid and the subsequent methoxylation.

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.
