| Abstract: | A 5-difluoromethoxy-2-mercapto-lH-benzimidazole is an important pharmaceutical intermediate. The early syn-
thesis method and the new pharmaceutical process which is based on p-acetamidophenol are introduced in this article. The new pharmaceutical process whose process flow is short and material is cheaper and easily available, made improvements on some process conditions of early methods, and it is more convenient to be commerciaslized. |
