What are the synthesis methods of N-Phenylimidazole?

The method of synthesizing N-phenylimidazole has been known for a long time. One method is to use imidazole and halobenzene as raw materials, add alkali agent, and make it undergo nucleophilic substitution reaction at a suitable temperature and reaction time. For example, take an appropriate amount of imidazole, dissolve it in an organic solvent, such as N, N-dimethylformamide (DMF), add halogenated benzene, such as bromobenzene or chlorobenzene, and then slowly add alkali agents such as potassium carbonate. Warm up to a certain extent, or 80-120 degrees Celsius, and continue to stir to fully react. After the reaction is completed, the product is purified by extraction, column chromatography, etc.

The second method uses aniline and glyoxal as starting materials. First, aniline and glyoxal are condensed under acid catalysis to form intermediate products. Commonly used acids, such as acetic acid, etc. This reaction may be carried out at room temperature to 60 degrees Celsius. After a certain period of time, a dehydrating agent is added to dehydrate and cyclize the intermediate product, and finally N-phenylimidazole is obtained.

There are also those who use o-phenylenediamine and benzoic acid as raw materials. Under specific conditions, the two first condense to form amide intermediates, and then react with intramolecular cyclization to obtain the target product. This process may require a suitable catalyst and reaction environment to promote the progress of the reaction and the generation of the product.
