Some common heterocyclic compound, 608-30-0, name is 2,6-Dibromoaniline, molecular formula is C6H5Br2N, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. category: bromides-buliding-blocks
In a 1 L three-necked flask, the raw material 2,6-dibromoaniline (25 g, 0.1 mol), iodobenzene (51 g, 0.25 mol), copper powder (7.0 g, 0.11 mol), potassium carbonate ( 34.5g, 0.25mol), o-dichlorobenzene (500mL), heated to 160 C under nitrogen protection, heat preservation reaction for 24 hours, cool to 25 C, suction filtration, 200g toluene rinse filter cake, collect filtrate, remove solvent The obtained crude product was purified by silica gel column chromatography. The eluent was petroleum ether: ethyl acetate=5:1, and the target product A01 was obtained in the form of 28.5 g, yield 70.7%.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 608-30-0, its application will become more common.
