Adding a certain compound to certain chemical reactions, such as: 6980-08-1, 4-Chloro-3-nitropyridin-2-amine, 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, 6980-08-1, blongs to pyridine-derivatives compound. Application In Synthesis of 4-Chloro-3-nitropyridin-2-amine

Step 1 A solution of 2-chloro-3-nitro-pyridin-4-amine (LXXXI) (1.5 g, 8.64 mmol), 2-(5-fluorothiophen-2-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (XCIV) (2.96 g, 12.96 mmol), Pd(dppf)Cl2 (632 mg, 0.86 mmol) and Cs2CO3 (5.63 g, 17.29 mmol) in dioxane (30 mL) and H2O (5 mL) was de-gassed and then heated to 100 C. under N2 for 3 h. TLC (PE:EtOAc=1:1) showed the starting material was consumed completely. The mixture was concentrated in vacuum to give a residue, which was purified by column chromatography to afford 4-(5-fluorothiophen-2-yl)-3-nitropyridin-2-amine (XCV) (800 mg, 3.34 mmol, 38.7% yield). ESIMS found C9H6FN3O2S m/z 240.1 (M+H).

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,6980-08-1, its application will become more common.
