Method for preparing pantoprazole nitrogen oxide

The invention provides a preparation method of pantoprazole nitrogen oxide, which is implemented according to the following steps: reacting 2-chloromethyl-3, 4-dimethoxypyridine hydrochloride servingas a raw material with m-chloroperoxybenzoic acid, and carrying out oxidization to prepare pyridine nitrogen oxide; and enabling the pyridine nitrogen oxide to react with 5-difluoromethoxy-2-mercapto-1H-benzimidazole to generate 5-difluoromethoxy-2-[(3, 4-dimethoxy-2-pyridyl) methyl] thio-1H-benzimidazole nitrogen oxide. The genetically toxic impurity pantoprazole nitrogen oxide of the pantoprazole sodium sesquihydrate is prepared by an economical and green method, the operation is simple and convenient, the condition is mild, and the product purity is high.
