To prepare 2-N-propyl-4-methyl-6- (1-methylbenzimidazole-2-yl) benzimidazole (BIM), the method is as follows:
First take an appropriate amount of 1-methyl-2-nitrobenzimidazole, place it in a reactor, add an appropriate amount of organic solvent, such as dimethylformamide (DMF), to help it dissolve and form a uniform solution.
Take another 2-chloro-4-methyl-6-nitroaniline, also place it in another vessel, and also dissolve it with DMF. Subsequently, the solution containing 2-chloro-4-methyl-6-nitroaniline was slowly added to the solution containing 1-methyl-2-nitrobenzimidazole under stirring. After adding, the reaction temperature was raised to about 120 ° C, and the reaction was continuously stirred to make the two fully react. During this process, the two underwent a nucleophilic substitution reaction to generate 2-N- (2-nitro-4-methyl-6-aniline) -1-methylbenzimidazole.
After the reaction is completed, the reaction solution is cooled to room temperature, and then slowly poured into a large amount of ice water, and solids are precipitated. Filtration with a Brinell funnel is used to collect solids and wash them repeatedly with deionized water to remove impurities to obtain a crude product.
This crude product is recrystallized in ethanol to obtain pure 2-N- (2-nitro-4-methyl-6-phenylamino) -1-methylbenzimidazole.
Then transfer this pure product into an autoclave, add an appropriate amount of ethanol as a solvent, and an appropriate amount of palladium carbon (Pd/C) as a catalyst. Add hydrogen, adjust the pressure in the kettle to about 2 MPa, heat up to 80 ° C, and continue to stir the reaction. Under this condition, a reduction reaction occurs, and the nitro group is reduced to an amino group to generate 2-N- (2-amino-4-methyl-6-anilinyl) -1-methylbenzimidazole.
After the reaction is completed, the kettle is cooled and reduced pressure, the palladium-carbon catalyst is filtered to remove, and the filtrate is distilled under reduced pressure to remove the ethanol solvent to obtain the remaining solid. The solid is recrystallized with ethyl acetate to obtain the refined product.
Finally, take the refined 2-N- (2-amino-4-methyl-6-phenylamino) - 1-methylbenzimidazole, put it into the reaction bottle, add an appropriate amount of propionyl chloride and acid binding agent, such as triethylamine. When stirring the reaction number at room temperature, the amino group and propionyl chloride are acylated to form 2-N-propyl-4-methyl-6- (1-methylbenzimidazole-2-yl) benzimidazole (BIM). After the reaction, the reaction solution was washed with dilute hydrochloric acid to remove excess acid binding agent, and then extracted with dichloromethane to collect the organic phase, dried with anhydrous sodium sulfate, filtered, and distilled under reduced pressure to remove dichloromethane. The final target product, BIM, can be further refined to improve its purity.

In terms of biosafety, the impact on organisms should be considered. Although the exact biological activity is not yet known, benzimidazoles are often biologically active or can interact with targets in organisms. If they enter the human body, they may interfere with the normal physiological functions of cells, such as affecting enzyme activities, destroying cell membrane structures, etc., which may damage human health, cause organ damage, allergic reactions and even cancer risk.
Environmental safety cannot be ignored. If this compound enters the environment, it may be difficult to be degraded naturally due to its chemical stability. Accumulate in soil and water bodies, or affect the balance of ecosystems, have adverse effects on the growth and development of animals and plants, destroy the food chain, and cause ecological disasters.
