Synthetic Route of 31827-94-8,Some common heterocyclic compound, 31827-94-8, name is 2-Bromo-1-(4-iodophenyl)ethanone, molecular formula is C8H6BrIO, 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.
Into a solution of the compound from step A1d (1.94 mmol at most) in acetonitrile (5 mL) and DIPEA (3 mL) was added 2-bromo-1-(4′-iodophenyl)ethanone (700 mg, 2.15 mmol). It was stirred at rt for 4 hours before concentration to a dark red oil, which was chromatographed (silica, EtOAc-hexanes) to afford the desired compound as a light yellow oil (643 mg, 66% over three steps). ESIMS m/z=400.03 [M-Boc+2H]+.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2-Bromo-1-(4-iodophenyl)ethanone, its application will become more common.
