Abstract:1-Methanesulfonyl-3-(1-methyl-5-nitroimidazol-2-yl)-2-imidazolidinone was obtained from 2-mercapto-1-methylimidazole by a four-steps reaction process including methylation, nitration, oxidation, and condensation. The structure of the product was confirmed using 1H NMR, 13C NMR, MS, and IR. The effects of factors including reaction temperature, mass of the catalyst, and molar ratio of raw materials on the reaction were investigated. The results of experiment showed that satranidazole was obtained with a yield of 21.6% under the optimum conditions. The producing process is easy to control with high yield and low cost, and it is suitable for industrial production.
Key words:satranidazole; nitroimidazole; synthesis
