Related Products of 96558-78-0,Some common heterocyclic compound, 96558-78-0, name is 3-Bromo-5-chlorophenylamine, molecular formula is C6H5BrClN, 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.
To a solution of 3-bromo-5-chloro-aniline (10 g, 48.4 mmol, 1 eq) and tert- butoxycarbonyl tert-butyl carbonate (12.7 g, 58.1 mmol, 13.4 mL, 1.2 eq) in 100 mL of THF was added K2CO3 (20.1 g, 145.3 mmol, 3 eq). The mixture was stirred at 40C for 12 hrs. The reaction mixture was concentrated under reduced pressure to remove THF. The residue was purified by column chromatography (S1O2, eluting with a gradient of petroleum ether/ethyl acetate=l/0 to 0/1) to give 6.1 g of compound 1 (19.90 mmol, 41.1% yield) as a white solid
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 3-Bromo-5-chlorophenylamine, its application will become more common.
