Simple exploration of 112671-42-8

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.

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. 112671-42-8, name is 4-Bromo-1-iodo-2-nitrobenzene, A new synthetic method of this compound is introduced below., COA of Formula: C6H3BrINO2

To a solution of 4-bromo-1 -iodo-2-nitrobenzene (66 g, 0.2 mol) in MeOH (700 mL) was added stannous chloride (226 g, 1 mol) at 0 C. The resultant mixture was heated to reflux (80 C) for 4 h. The solvent was removed under reduced pressure, and then the residue was diluted with ethyl acetate (1 L), washed with H2O (1 L), dried over sodium sulfate, concentrated to give a residue which was purified by column chromatography (eluent: petroleum ether: ethyl acetate= 20:1 ) to give 5-bromo-2-iodoaniline (39 g, 65%) as a white solid. LCMS (Method B): 2.27 min m/z [MH]+=298.1 ; 300.1
