2-Bromo-4-nitro-1H-imidazole - Reference Information

Application 2-bromo-4-nitroimidazole is an intermediate in organic synthesis and a pharmaceutical intermediate, can be used in laboratory research and development process and chemical and pharmaceutical synthesis process.
Introduction 2-bromo-4-nitroimidazole is a pale yellow to off-white powder that can be used as a pharmaceutical intermediate.
synthesis method 4-nitroimidazole (VIII) as the starting material, 2, 5-dibromonitroimidazole (XI) is obtained by reaction with brominating reagent in water and in the presence of alkali metal bicarbonate, the latter is reacted with an iodinated reagent in an aprotic solvent to give 2-bromo-5-iodo-2-nitroimidazole (XV). 2-bromo-5-iodo-2-nitroimidazole (XV) is further reacted with a phosphorus reduction reagent in an alcoholic solvent to obtain the target product 2-bromo-4-nitroimidazole (II).
