Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 1003-21-0, name is 5-Bromo-1-methyl-1H-imidazole, This compound has unique chemical properties. The synthetic route is as follows., Computed Properties of C4H5BrN2
General procedure: To a solution 5-bromo-1-methyl-(1H)-imidazole (180mg, 1.13 mmol) in THF (10 mL) HMPA (Hexamethylphosphoramide)was added (130 mg, 0.75 mmol) followed by t-BuLi (170 mg, 2.6 mmol) at -78oC, the resulted mixture wasallowed to stir at rt for 1 h. Then it was cooled back to -78oCand amidosulphone 4a-4j (0.75 mmol) was added in THF (5mL) slowly. The reaction mixture was slowly allowed to stirat rt for 2 h. Then, the reaction mixture was quenched withNH4Cl and extracted into EtOAc. The combined organiclayers were dried over Na2SO4 and distilled in vacuum to getcrude compounds 5a-5j and were purified by column chromatography using 5 % MeOH in DCM to get the final compounds5a-5j with 59-65 % yield.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 1003-21-0.
