1 - tosyl - 1H - benzoimidazole is an important class of organic compounds. There are several common synthesis methods.
First, it is synthesized from o-phenylenediamine and p-toluenesulfonyl chloride in a suitable reaction environment. Dissolve o-phenylenediamine in a suitable solvent, such as alcohol or ether solvent, and slowly add p-toluenesulfonyl chloride. During this process, pay attention to the temperature and pH of the reaction. Usually control the temperature in the low temperature range, such as between 0-10 ° C, to avoid side reactions. And in an alkaline environment, if an appropriate amount of pyridine or triethylamine is added, the reaction can be promoted. The condensation reaction of the two can obtain 1-tosyl-1H-benzoimidazole.
Second, o-nitroaniline can also be used as a starting material. First, o-nitroaniline is converted into o-phenylenediamine by reduction reaction. This reduction step is often carried out in an acidic medium with iron powder, zinc powder, etc. After obtaining o-phenylenediamine, the target product is synthesized by reacting with p-toluenesulfonyl chloride as described above.
Or, 2-halogenated nitrobenzene and p-toluenesulfonamide are used as raw materials. In the presence of alkaline conditions and catalysts, the nucleophilic substitution reaction occurs between the two, followed by a reduction step, the nitro group is reduced to an amino group, and then cyclized to obtain 1-tosyl-1H-benzoimidazole. In this synthesis path, the choice of catalyst and the control of reaction conditions are very critical, such as the type and dosage of catalyst, as well as the temperature and time of the reaction, which will affect the yield and purity of the product.
