First, phthaleamine and acetylacetone are used as raw materials. Under appropriate reaction conditions, the condensation reaction can occur. First, phthaleamine and acetylacetone are placed in a reaction vessel in a certain proportion, and an appropriate amount of catalyst is added, such as protonic acid or Lewis acid. Common protonic acids, such as p-toluenesulfonic acid; Lewis acid, such as ZnCl ², etc. The reaction temperature control is critical, and generally needs to be carried out under heating conditions, with a temperature range of roughly 120-180 ° C. This reaction environment is preferably protected by inert gas to avoid oxidation of raw materials and products. Under this condition, the amino group of o-phenylenediamine and the carbonyl group of acetylacetone undergo nucleophilic addition, and then dehydrate and cyclize to form 2,6-dimethyl-1H-benzimidazole.

The alkaline environment is conducive to the reaction, and bases such as sodium hydroxide or sodium carbonate can be used to adjust the pH value. During the reaction, an intermediate is formed first, and then it is cyclized within the molecule to finally generate the target product 2,6-dimethyl-1H-benzimidazole. This path has a little more steps, but each step has better reaction selectivity. If the operation is proper, a higher purity product can be obtained.
Third, phthalonitrile and acetone are used as raw materials. Under the catalyst and specific reaction conditions, phthalonitrile is first added to acetone, followed by a series of processes such as hydrolysis and cyclization to obtain 2,6-dimethyl-1H-benzimidazole.
