To prepare 1- [ (4 -chlorophenyl) methyl] -2 - (1 -pyrrolidinyl methyl) -1H -benzimidazole monohydrochloride, there are many methods, and the common ones are selected.
First, start with a suitable benzimidazole derivative, and first react with a halogenated hydrocarbon containing (4 -chlorophenyl) methyl under base catalysis to form a 1- [ (4 -chlorophenyl) methyl] -benzimidazole intermediate. Then, this intermediate is reacted with 1-pyrrolidine methylation reagent, such as 1- (halomethyl) pyrrolidine, under suitable conditions to obtain 1 - [ (4-chlorophenyl) methyl] -2 - (1-pyrrolidine methyl) -1H -benzimidazole. Finally, it is treated with hydrogen chloride gas or hydrochloric acid solution to obtain the monohydrochloride of the target product. In this process, the selection of base, reaction temperature and time need to be carefully adjusted to increase the yield and purity of the product.
Second, a route can be designed to build a benzimidazole skeleton first. During the construction process, (4-chlorophenyl) methyl and 1-pyrrolidinyl methyl substituents are ingeniously introduced. For example, by reacting o-phenylenediamine containing a specific substituent with a suitable carboxylic acid or its derivatives, through cyclization, substitution and other series reactions, 1 - [ (4-chlorophenyl) methyl] -2 - (1-pyrrolidinyl methyl) -1H - benzimidazole can be obtained. The key to this route is the order of reaction steps and the optimization of reaction conditions in each step to avoid side reactions and obtain high-purity products.
Third, there is also a method with catalytic coupling reaction as the core. Transition metal catalysis is used to couple benzimidazole derivatives containing halogen atoms with (4-chlorophenyl) methyl borate or the like to introduce (4-chlorophenyl) methyl. Subsequently, 1-pyrrolidyl methyl is introduced through a similar method, and the final hydrochlorination product is obtained. This catalytic coupling method requires the selection of efficient catalysts and ligands, and precise control of the reaction conditions to achieve a good reaction effect.
