| titleOfInvention | Process for production of benzimidazole derivative salt precipitate |
| abstract | The present invention provides a process for the production of a 2-[{4-(3-methoxypropoxy)-3-methylpyridin-2-yl}methylsulfinyl]-1 H-benzimidazole alkali metal salt (1), which is a drug or an intermediate for the production of a drug, the process not requiring large-scale equipment and being excellent in terms of workability, operability and energy conservation. According to the present invention, there is disclosed a process for the production of a salt precipitate represented by formula (1) n n(wherein B represents an alkali metal ion), the process comprising the steps of:n dissolving the compound represented by formula (2) n nin a first organic solvent and adding an alkali metal hydroxide, or dissolving the alkali metal hydroxide in the first organic solvent and adding the compound represented by formula (2); andn further adding a second organic solvent to a reaction mixture obtained. |
