The present work details the journey towards development of a simple and cost-viable process for large-scale synthesis of rabeprazole sodium substantially free from the impurities. The detailed study of different parameters affecting the quality and yield percentage of the compound has been presented. Yield is increased from 40% (reported process) to 75% with the improved process at sulfoxidation stage.

The invention discloses a method for preparing optically-pure Rabeprazole. The method is used for preparing a chiral 2-[[4-(3-methoxypropoxy)-3-methylpyrid-2-yl]methylsulfinyl]-1H-benzimidazole compound (Rabeprazole), which is present in a single-enantiomer form or rich-enantiomer form, in an enantioselective manner. The same effects, i.e., identical enantioselectivity and conversion ratio can be achieved through complexing a tartaric acid diamide ligand and titanium and adding an organic-base additive or not in the presence of water. The invention further provides a method for preparing a sodium salt from the obtained Rabeprazole.
