Synthetic method of 2-n-propyl-4-methylbenzimidazole-6-carboxylic acid

The invention relates to a synthetic method of 2-n-propyl-4-methylbenzimidazole-6-carboxylic acid. The synthetic method comprises the following steps: through nitric acid/concentrated sulfuric acid nitrification reaction of 3,5-dimethylnitrobenzene, generating an intermediate product II, namely 3,5-dimethyl-1,2-dinitrobenzene; performing Pd/C catalytic hydrogenation reaction on the intermediate product II in an ethanol solution to obtain an intermediate product III, namely 3,5-dimethyl-1,2-phenylenediamine; enabling the intermediate product III to react with N-butyric acid in a polyphosphoric acid solution to obtain an intermediate product IV, namely 2-n-propyl-4,6-dimethylbenzimidazole; performing cobalt salt air liquid-phase oxidation reaction on the intermediate product IV in an acetic acid solution to obtain a product V, namely the 2-n-propyl-4-methylbenzimidazole-6-carboxylic acid. The synthetic method provided by the invention has the benefits that the operation is simple, raw materials are easy to obtain, a used solvent can be recycled, the product content can reach 95 percent or above, the yield is up to 73.2 percent, the pollution is less, and the suitability for industrial production is realized.
