The origin of a common compound about 3430-26-0

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,3430-26-0, its application will become more common.

Synthetic Route of 3430-26-0, 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. 3430-26-0, name is 2,5-Dibromo-4-methylpyridine. A new synthetic method of this compound is introduced below.

Step A: 5-Bromo-2-iodo-4-methyl-pyridine To a solution of 2,5-dibromo-4-methylpyridine (2 g) in acetonitrile (40 ml) at room temperature under argon were added sodium iodide (4.8 g) then acetyl chloride (0.94 g). After 3 hours stirring at room temperature the white solid formed was filtered off and the filtrate was neutralized with aqueous saturated solution of sodium hydrogenocarbonate. The organic phase was dried over sodium sulfate and concentrated in vacuo. The residue was purified by column chromatography (ethyl acetate/cyclohexane) to afford the title product as a brown solid (2.04 g). 1H-NMR (CDCl3, 400 MHz): 8.40 (s, 1H), 7.60 (s, 1H), 2.30 (s, 3H),

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,3430-26-0, its application will become more common.
