Adding a certain compound to certain chemical reactions, such as: 633328-33-3, 3-Bromo-1H-pyrazolo[4,3-b]pyridine, 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, SDS of cas: 633328-33-3, blongs to pyridine-derivatives compound. SDS of cas: 633328-33-3
To a stirred solution of 3-bromo-1 H-pyrazolo[4,3-b]pyridine (500 mg, 2.52 mmol) in DMF, NaH (60%) (201 mg, 5.04 mmol) was added at 0C and it was stirred for 15min. Then, 1 -bromo-2-methoxyethane (420 mg, 3.02 mmol) was added and the reaction mixture was stirred at rt for 2h. The reaction mixture was quenched with water and extracted with EtOAc. The organic layer was dried over anhydrous Na2S04, and it was concentrated under reduced pressure. The crude compound was purified by flash column chromatography on 230-400 silica using 45% EtOAc in pet ether as an eluent to afford the title compound (430 mg, 66%) as a gummy solid.LC-MS (method 24): R, = 2.63 min; m/z = 258.01 (M+2H+),
At the same time, in my other blogs, there are other synthetic methods of this type of compound,633328-33-3, 3-Bromo-1H-pyrazolo[4,3-b]pyridine, and friends who are interested can also refer to it.
