To prepare methyl-1H-benzimidazole-6-carboxylate, there are three methods. First, with 6-carboxyl-1H-benzimidazole as the starting material, it is heated with methanol under strong acid catalysis, and the esterification reaction is carried out. Among them, sulfuric acid and p-toluenesulfonic acid can be used as catalysts, and the two have strong catalytic ability, which can promote the reaction to speed up. After the reaction is completed, the pure product can be obtained through neutralization, extraction, distillation and other steps.
Second, 1H-benzimidazole-6-carboxylic acid ethyl ester is used as raw material to react with sodium methoxide in methanol solution, which is a method of ester exchange. Sodium methoxide has good activity, which can make ethyl ester group easy to methoxy group to obtain the target product. After acidification, separation and purification, pure methyl-1H-benzimidazole-6-carboxylate is obtained.
Third, the reaction of 6-halo-1H-benzimidazole with dimethyl malonate under alkali catalysis first obtains the intermediate containing carboxyl ester, and then hydrolyzes and decarboxylates to obtain the final product. This approach is slightly complicated, but the raw materials are easy to obtain, which is also a feasible method. All methods have advantages and disadvantages. In actual preparation, when considering the availability of raw materials, cost, yield and product purity, etc., to choose the best method.
