To prepare 2- ((R) -2-methylpyrrolidine-2-yl) -1H-benzimidazole-4-formamide, the following method can be followed.
The first is the choice of starting materials. Commonly used, the compound containing benzimidazole and pyrrolidine structure is used as the base. For example, a suitably substituted benzimidazole derivative and a chiral pyrrolidine derivative can be selected as the starting substance of the reaction.
One method is through nucleophilic substitution. If a suitably halogenated benzimidazole derivative can react with (R) -2-methylpyrrolidine-2-amine. In this reaction, the nitrogen atom of the amine group is nucleophilic and can attack the carbon attached to the halogen atom of the halogenated benzimidazole. The halogen ions leave, and then form carbon-nitrogen bonds to obtain the target molecular structure. The reaction needs to choose a suitable base to grab the halogenated hydrogen generated by the reaction, promote the positive progress of the reaction, and choose a suitable solvent, such as N, N-dimethylformamide (DMF), dimethyl sulfoxide (DMSO), etc., in order to facilitate the dissolution of the reactants and the reaction.
Furthermore, the cyclization reaction strategy can be used. If there is a suitable linear precursor, containing the relevant functional groups of benzimidazole and pyrrolidine, under suitable conditions, it will undergo molecular inner cyclization. For example, when a linear molecule has an amino group at one end and a carbonyl group or a carboxyl group that can react with an amino group to form a ring at the other end, under the catalysis of an acid or base, through condensation and other steps, benzimidazole and pyrrolidine are formed into a ring system, and then the target product is appropriately modified.
Or a reaction catalyzed by transition metals can be used. For example, a coupling reaction catalyzed by palladium, a borate ester or halide containing benzimidazole structure, and a substrate containing (R) -2-methylpyrrolidine-2-yl halide or olefin, in the presence of a palladium catalyst, ligand and base, the formation of carbon-carbon or carbon-nitrogen bonds is realized to construct the target compound. In this process, the activity of the palladium catalyst and the structure of the ligand have a great influence on the selectivity and yield of the reaction, so fine screening is required.
After the reaction is completed, the product often contains impurities, so it needs to be separated and purified. According to the properties of the product and impurities, extraction, column chromatography, recrystallization and other methods can be selected to obtain purified 2- ((R) -2-methylpyrrolidine-2-yl) -1H-benzimidazole-4-formamide.
