Adding a certain compound to certain chemical reactions, such as: 14432-12-3, 4-Amino-2-chloropyridine, 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 14432-12-3, blongs to pyridine-derivatives compound. Product Details of 14432-12-3
2-Chloro-pyridin-4-ylamine 1b* (3.2 g, 0.025 mol) and sodium acetate (4.1 g, 0.05 mol) were stirred in acetic acid (20 ml). A solution of iodine monochloride (4.1 g, 0.025 mol) in acetic acid (10 ml) was added and the reaction mixture was heated to 70 C for approximately 3 h (NB: solution at -50 C, brown colour faded and precipitate formed as the reaction proceeded). The reaction mixture was cooled to room temperature, then poured onto water (700 ml), and extracted with EtOAc. The organic layer was carefully washed with a solution of Na2CO3 followed by a solution of Na2S2O3, dried over MgSO4 and concentrated in vacuo. The crude product was purified by column chromatography using 10% EtOAc in DCM to yield 2-chloro-5-iodo-pyridin-4-ylamine 2b* (2.60 g, 40%). 1H NMR (400 MHz, CDCl3) delta (ppm): 8.34 (1 H, s), 6.63 (1 H, s), 4.78 (2 H, s).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,14432-12-3, 4-Amino-2-chloropyridine, and friends who are interested can also refer to it.
