The synthesis method of 2-phenyl-1H-benzimidazole-6-sulfonic acid is explained to Youshi, which is also the key to organic synthesis. To obtain this compound, a number of paths are often followed.
First, take benzimidazole as the base and use the method of sulfonation. Take benzimidazole first, choose an appropriate solvent, such as dichloromethane or N, N-dimethylformamide, and dissolve it. Then add a sulfonating agent, such as fuming sulfuric acid or chlorosulfonic acid. During the reaction, strictly control the temperature, usually between low temperature and medium temperature, such as 0 ° C to 50 ° C, to prevent side reactions from clumping. The amount of sulfonating reagent must also be considered. According to the stoichiometric ratio, a slight excess can promote the completion of the reaction. After the reaction is completed, it is neutralized in alkali solution, such as sodium hydroxide or sodium carbonate solution, and the precipitates are purified by recrystallization. Pure 2-phenyl-1H-benzimidazole-6-sulfonic acid can be obtained.
Second, start with benzene derivatives. Choose a suitable benzene series, and there are groups that can be converted into benzimidazole rings. First, through a condensation reaction, it forms a benzimidazole ring structure. If condensed with o-phenylenediamines, under acid catalysis or heating conditions, promote cyclization. After the sulfonation step, the method is as described above, through sulfonation, neutralization, purification, etc., to obtain the target product.
Third, by the method of transition metal catalysis. With a substrate containing benzene ring and potential benzimidazole structure, a transition metal catalyst such as palladium and copper is selected, and the ligand is coordinated. Under suitable reaction conditions, the benzene ring is coupled with a nitrogen-containing reagent to form a benzimidazole ring, and then sulfonated. This way, the reaction conditions need to be precisely regulated. Due to the strict requirements of transition metal catalysis on substrates, catalysts, ligands and reaction environments, it has good selectivity and can obtain high-purity products.
All synthesis methods have their own advantages and disadvantages, and need to be carefully selected according to the availability of raw materials, cost considerations, product purity requirements, etc. To carry out synthesis, we must abide by the regulations of chemistry and strictly follow the experimental procedures to prepare this compound.
