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, Product Details of 89415-54-3, blongs to pyridine-derivatives compound. Product Details of 89415-54-3
A solution of 5-bromo-N*2*-methyl-pyridine-2 3-diamine (Stage 67.1.4, 960 mg, 4 75 mmol) in triethylorthoacetate (Aldrich, Buchs, Switzerland, 25 ml) was stirred for 38 5 h at 140C. The reaction mixture was evaporated to dryness. The residue was dissolved in EtOAc and washed with saturated aqueous NaHCO3. The aqueous layer was extracted with EtOAc and the combined organic layers washed with brine, dried over Na2SO4, filtered and evaprated. The crude product was dry loaded on silica gel and purified by MPLC (DCM/MeOH 0% – 4%) to give the title compound as a brown solid (HPLC. tR 1 95 mm (Method A); M+H = 226, 228 MS-ES).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,89415-54-3, 5-Bromo-N2-methylpyridine-2,3-diamine, and friends who are interested can also refer to it.
