There are various ways to synthesize 6-bromo-1H-benzimidazole-2-carboxylic acid. First, it can be started from o-phenylenediamine and diethyl bromomalonate. First, the o-phenylenediamine and diethyl bromomalonate are heated and refluxed in a suitable solvent, such as ethanol, with an appropriate amount of base, such as potassium carbonate as a catalyst. In this step, the amino group of o-phenylenediamine interacts with the ester group of diethyl bromomalonate, and undergoes nucleophilic substitution to form an intermediate product. Afterwards, the resulting intermediate product is heated and hydrolyzed in an acidic environment, such as dilute hydrochloric acid. After hydrolysis, it is acidified to promote the formation of carboxyl groups, and finally 6-bromo-1H-benzimidazole-2-carboxylic acid is obtained.
Furthermore, 4-bromo-1,2-phenylenediamine and oxalic acid can also be used as raw materials. 4-bromo-1,2-phenylenediamine and oxalic acid are placed in a high boiling point solvent, such as polyphosphoric acid, and heated to temperature. Under this condition, the amino group of 4-bromo-1,2-phenylenediamine undergoes a condensation reaction with oxalic acid to form a benzimidazole ring structure, and a part of the oxalic acid is converted to a carboxyl group, thereby preparing the target product.
Or use 6-bromo-1H-benzimidazole as the starting material. First, 6-bromo-1H-benzimidazole is mixed in an appropriate solvent, such as dichloromethane, with an appropriate amount of base, such as sodium hydride. Then, a halogenated carboxylate, such as ethyl chloroacetate, is slowly added dropwise. During this reaction, the base captures the hydrogen on the 6-bromo-1H-benzimidazole nitrogen atom to form a carboanion, which then undergoes a nucleophilic substitution reaction with the halogenated carboxylate. After the reaction is completed, the ester group is hydrolyzed with acid to obtain 6-bromo-1H-benzimidazole-2-carboxylic acid.
