1-Bromo-2,4-dimethoxybenzene - Reference Information
| Application | 2,4-dimethoxybromobenzene can be used as an intermediate in pharmaceutical synthesis. It has been reported in the literature that it can be obtained by 2, 4-dimethoxybenzene bromide or by 2, 4-dimethoxybenzene methylation. |
| preparation method | 2,4-dimethoxybenzene and THF are added to the round bottom flask, dibromohydantoin (DBDMH) is added at room temperature, and after adding, continue stirring at room temperature for 6 hours. TLC monitoring, after the reaction is completed, the solvent is evaporated in vacuum, water is added to the flask, the mixture is extracted with ethyl acetate, anhydrous sodium sulfate is dried, and evaporated to obtain colorless transparent crystal compound 2, 4-dimethoxybromobenzene with 96% yield. |
