AbstractAn improved method for the preparation of benzimidazole-2-sulfonic acids from 2-mercaptobenzimidazoles has been developed which utilizes aqueous sodium percarbonate. 2-Chlorobenzimidazoles were obtained in high yield from the corresponding sulfonic acids upon reaction with PCl5in POCl3on a gram-mole scale.‡ Dedicated to Henry Koppel. |
