Second, o-nitroaniline is used as the starting material. First, o-nitroaniline is reduced to iron powder, hydrochloric acid, etc. as reducing agents to obtain o-phenylenediamine. Then it is reacted with p-toluenesulfonyl chloride in an alkaline environment, such as pyridine as a solvent and acid binding agent, and reacted at room temperature. The sulfonyl group of p-toluenesulfonyl chloride is combined with the amino group of o-phenylenediamine, and then cyclized by heating, and the target product can also be obtained. The product can be separated and purified by column chromatography, using silica gel as the stationary phase, a suitable eluent such as a mixture of petroleum ether and ethyl acetate. The fraction containing the target product is collected, and the solvent is evaporated to obtain a pure 2-methyl-1-p-toluenesulfonyl-1H-benzimidazole.
There is also a method of using o-phenylenediamine and p-toluenesulfonyl hydrazide as raw materials. Under the protection of inert gas, such as nitrogen atmosphere, the raw material is dissolved in a suitable organic solvent such as dichloromethane, and an appropriate amount of initiator is added. It is heated to the re The reaction mechanism is that p-toluenesulfonyl hydrazide decomposes to produce an active intermediate, which gradually reacts with o-phenylenediamine and cyclizes to form the target product. The desired 2-methyl-1-p-toluenesulfonyl-1H-benzimidazole can be obtained through subsequent extraction, drying and concentration steps.
