Methyl 7-methyl-2-propyl-1H-benzimidazole-5-carboxylic acid has been synthesized in ancient times, and there are various ways.
First, it can be obtained by carboxyl esterification of benzimidazole compounds. First, take a suitable 7-methyl-2-propyl-1H-benzimidazole-5-carboxylic acid and place it in a clean reaction vessel. The vessel needs to be dried to prevent moisture from interfering with the reaction. Then, add an appropriate amount of methanol as an esterification agent. The amount of methanol, when accurately prepared according to the amount of carboxylic acid and stoichiometric ratio, is usually slightly excessive to promote the reaction to move in the direction of esterification. At the same time, an appropriate amount of concentrated sulfuric acid is added as a catalyst. Concentrated sulfuric acid has high catalytic activity and can accelerate the process of esterification reaction, but the dosage should not be too much, otherwise it is easy to cause side reactions. Under mild heating conditions, such as oil bath heating, the reaction system is maintained at a suitable temperature range of about 60-80 ° C. This temperature is not only conducive to the improvement of the reaction rate, but also avoids the decomposition of the product due to excessive temperature. During the reaction process, constant stirring is required to ensure that the reactants are fully contacted and accelerate the reaction process. After the reaction is completed, using conventional separation and purification methods, such as vacuum distillation, column chromatography, etc., to remove unreacted raw materials, catalysts and by-products, pure 7-methyl-2-propyl-1H-benzimidazole-5-carboxylic acid methyl ester can be obtained.
Second, from the perspective of constructing a benzimidazole ring. First select a suitable o-phenylenediamine compound and a propyl-substituted carboxylic acid derivative, and carry out a condensation cyclization reaction under appropriate reaction conditions. In the reaction system, a suitable dehydrating agent, such as dicyclohexyl carbodiimide (DCC), needs to be added to promote the cyclization reaction. The choice of reaction solvent is also crucial. Common organic solvents such as toluene and dichloromethane need to be screened according to the solubility and reaction characteristics of the reactants. During the reaction process, the reaction process can be closely monitored by means of thin-layer chromatography (TLC). After the cyclization reaction is completed, the obtained benzimidazole derivative is modified by carboxyl esterification. The method is similar to the above esterification reaction. After subsequent separation and purification, the target product can also be obtained.
Third, some novel synthesis strategies can also be adopted. For example, the reaction path catalyzed by transition metals can be used. With suitable transition metal catalysts, such as palladium, copper and other metal complexes, the coupling reaction between related substrates was catalyzed to construct a benzimidazole skeleton, and substituents such as methyl and propyl were introduced synchronously, and then the carboxyl group was esterified. Although this method requires precise control of reaction conditions and catalyst dosage, it has the advantages of high reaction selectivity and simple steps. After a series of reaction operations, separation and purification, 7-methyl-2-propyl-1H-benzimidazole-5-carboxylate was finally successfully synthesized.

7-Methyl-2-propyl-1H-benzimidazole-5-carboxylic acid methyl ester, which is an organic compound. Looking at its physical properties, at room temperature, it is mostly in the state of solid, white or off-white crystalline powder. Due to the strong force between molecules, the aggregation morphology is stable. Its melting point is in a specific range, but the exact value varies due to factors such as purity, about 100 ° C - 120 ° C. This melting point range is derived from the lattice energy formed by the interaction of benzimidazole ring, methyl, propyl and ester groups in the molecular structure.
Its boiling point data is difficult to determine accurately, because it may decompose at high temperature, it is roughly estimated to be around 300 ° C - 350 ° C. This boiling point value reflects that high energy is required between molecules to overcome the interaction force to achieve gasification. The substance is insoluble in water, and it is difficult for water molecules to form effective interactions with it due to the large proportion of hydrophobic groups in its molecular structure, such as benzimidazole ring, methyl and propyl.
But it is soluble in common organic solvents, such as ethanol, dichloromethane, acetone, etc. In ethanol, it is dissolved by Van der Waals force and possible weak hydrogen bond between molecules and ethanol; in dichloromethane, due to the principle of similar miscibility, the intermolecular forces between the two are miscible; acetone can also be used as a good solvent due to similar structure and force. These solubility characteristics are of great significance in the process of organic synthesis, separation and purification, and preparation of preparations.
