Related Products of 850663-54-6, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 850663-54-6, name is 4-Chloro-5-nitropyridin-2(1H)-one. A new synthetic method of this compound is introduced below.

Into a 250 mL 3 -necked round-bottom flask purged and maintained with nitrogen was added a solution of 4-chloro-5-nitropyridin-2-ol (1 1.5 g, 65.9 mmol) in CH3CN (1 10 mL), followed by addition of POBr3 (23.1 g). The resulting solution was stirred at 80 C for 2 hours. The solids were filtered out and the filtrate was concentrated under vacuum. The residue was suspended in 500 mL of ice water. The resulting solids were collected by filtration and dried under vacuum to afford 2,4- dibromo-5-nitropyridine (7.66 g, 41.1%) as a light yellow solid, which was carried forward without purification.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,850663-54-6, its application will become more common.
