Adding a certain compound to certain chemical reactions, such as: 89415-54-3, 5-Bromo-N2-methylpyridine-2,3-diamine, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, name: 5-Bromo-N2-methylpyridine-2,3-diamine, blongs to pyridine-derivatives compound. name: 5-Bromo-N2-methylpyridine-2,3-diamine
To a solution of 5-bromo-N2-methylpyridine-2,3-diamine (14 g, 69 mmol) in DMF (702 mL) at room temperature was added CDI (29 g, 180 mmol). The reaction mixture was stirred for 16 h. LCMS analysis of the crude reaction mixture showed that the reaction was not complete, and the resultant residue was re-dissolved in THF and CDI (11.2, 69 mmol) was added. The reaction mixture was stirred at 60 C for 16 h. The reaction mixture was quenched with water and diluted with Et2O. The suspension was filtered and the resulting solid was washed with Et2O and dried under vacuum to yield the title compound as a black solid (15.8 g, 35.7 mmol), which was used in the next step without further purification. MS (ESI): mass calcd. for C7H6BrN3O, 226.97; m/z found, 227.0 [M+H]+.
The synthetic route of 89415-54-3 has been constantly updated, and we look forward to future research findings.
