The synthesis method of 2-amino-5-bromo-benzimidazole is described in many ancient books. One method is to start with phthalamine and 5-bromo-1,2-phthalic anhydride. First, phthalamine and 5-bromo-1,2-phthalic anhydride are mixed in a suitable solvent such as glacial acetic acid. Under heating conditions, the condensation reaction between the two occurs. This process requires careful regulation of temperature to make the reaction proceed smoothly, about 100-120 ℃ for a continuous reaction number of times. After the reaction is completed, the crystals are cooled and precipitated, and then recrystallized with an appropriate solvent to obtain pure 2-amino-5-bromobenzimidazole.
Another method is to use 4-bromo-1,2-dinitrobenzene as the starting material. First, it is reduced with a suitable reducing agent, such as a mixed system of iron powder and hydrochloric acid, to obtain 4-bromo-1,2-diaminobenzene. Then, 4-bromo-1,2-diaminobenzene is mixed with urea and cyclized at a high temperature, such as 180-200 ° C. This reaction needs to be protected by an inert gas to avoid the risk of oxidation. After the reaction is completed, 2-amino-5-bromobenzimidazole can also be obtained after cooling, separation, purification and other operations.
There are those who use 2-nitro-5-bromoaniline as the starting material. First reduce it to 2-amino-5-bromoaniline, which can be reduced by means such as palladium-carbon hydrogenation. Then, 2-amino-5-bromoaniline reacts with formic acid or its derivatives under heating conditions to form 2-amino-5-bromobenzimidazole through cyclization. This process also requires attention to the control of reaction conditions, such as temperature, reaction time, and the proportion of reactants, in order to achieve optimum yield and purity.
