The synthesis method of 1H-benzimidazole-2-ethanol has always been valued by chemical experts. There are many methods, each with ingenuity.
One is to use o-phenylenediamine and glycolic acid as raw materials, and the two are co-placed in the reactor under suitable reaction conditions. First adjust the acid and base of the reaction system, using acid or base as catalyst, common such as hydrochloric acid, sulfuric acid or sodium hydroxide. Control the reaction temperature in a specific range, about 150-200 ° C, heat and stir, and the two are condensed to gradually generate 1H-benzimidazole-2-ethanol. The raw materials are easy to obtain in this way, but the reaction conditions are slightly harsh, and precise temperature control and catalyst amount are required.
Second, o-nitroaniline is used as the starting material. First, o-nitroaniline is reduced to o-phenylenediamine. The commonly used reducing agent is the combination of iron filings and hydrochloric acid, or hydrogen is reduced under the action of catalysts such as palladium and carbon. After obtaining o-phenylenediamine, it is condensed with glycolic acid by the previous method. This path is reduced in one step, but o-nitroaniline has a wide range of sources and the cost may be reduced.
Third, 2-halo benzimidazole is reacted with sodium ethanol. In an organic solvent such as N, N-dimethylformamide, 2-halobenzimidazole and sodium ethanol undergo nucleophilic substitution reaction at appropriate temperature, and the halogen atom is replaced by ethoxy group, and then hydrolyzed to produce 1H-benzimidazole-2-ethanol. The reaction steps of this route are simple, but the preparation of 2-halobenzimidazole may require different efforts.
All synthesis methods have their own advantages and disadvantages. Users should choose carefully according to the actual situation, such as raw material cost, reaction conditions, product purity, etc., in order to obtain this compound efficiently.

1H-benzimidazole-2-ethanol is an organic compound. When using it, all precautions must be kept in mind.
