Abstract
By using 2-mercapto-1H-benzimizadole and 2-chloromethyl-4-(3-methoxy-propoxy)-3-methylpyridium chloride as raw materials,2-[{4-(3-methoxypropoxy)-3-methylpyridine-2-yl}methylthio]-1H-benzimidazole was synthesized.After oxidation and neutralization,the target product sodium salt of 2-[{4-(3-methoxypropoxy)-3-methylpyridine-2-yl}methylsulfinyl]-1H-benzimidazole was produced with a total yield of 66 %.The structure of the product was confirmed by the analysis of IR,1H NMR and MS.
