Second, it is also feasible to react with N-methyl phthalamine and aldehyde compounds. This reaction requires the help of a specific catalyst to proceed efficiently. Mix N-methyl phthalamine and aldehyde in an appropriate proportion, add the catalyst, and at a suitable temperature and reaction environment, the two will undergo condensation and cyclization to form the target product. After the reaction is completed, the product is separated by distillation, extraction and other means, and purified to obtain high-purity 1-methyl-1H-benzimidazole.
Third, some more complex organic synthesis paths can also be used, such as using a specific nitrogen-containing heterocyclic compound as the starting material and converting it through a multi-step reaction.
