Application of 5458-84-4,Some common heterocyclic compound, 5458-84-4, name is 1-Iodo-2-methoxy-4-nitrobenzene, molecular formula is C7H6INO3, 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 1-iodo-2-methoxy-4-nitrobenzene (1.0 g, 3.6 mmol) in dichioromethane was added BBr3 solution (1 M, 10 mL) at -78 C. The solution stirred at that temperature for two hours and then warmed to room temperature overnight. Water was added at 0 C and the mixture was extracted with ethyl acetate, dried over Na2SO4 and concentrated in vacuo. The crude product was purified by flash chromatography on silica gel column with ethyl acetate-hexane (1:20), to give 2-iodo-5-nitrophenol as a yellow powder (300 mg, 3 1%). LCMS: m/z 263.8 [M-Hj.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 1-Iodo-2-methoxy-4-nitrobenzene, its application will become more common.
