Adding a certain compound to certain chemical reactions, such as: 154237-70-4, 4-Bromo-3-cyanopyridine, 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, Computed Properties of C6H3BrN2, blongs to pyridine-derivatives compound. Computed Properties of C6H3BrN2
Into a 20 mL vial were added dimethylamine (295.63 mg, 6.557 mmol, 2.00 equiv) , 4-bromopyridine-3-carbonitrile (600 mg, 3.279 mmol, 1 equiv) and K 2CO 3 (1.36 g, 9.836 mmol, 3.00 equiv) at room temperature. The resulting mixture was stirred for 2 h at 40. The resulting mixture was filtered, the filter cake was washed with DCM (2×20 mL) . The filtrate was concentrated under reduced pressure. The residue was purified by Prep-TLC (EtOAc) to afford 4- (dimethylamino) pyridine-3-carbonitrile (470mg, 97.40%) as an off-white solid (crude) . 1H-NMR (400 MHz, CDCl 3) delta 3.26 (6H, s) , 6.55 (1H, d) , 8.23 (1H, d) , 8.47 (1H, s)
The synthetic route of 154237-70-4 has been constantly updated, and we look forward to future research findings.
