Bromine → 2-Bromo-1-(3-nitrophenyl)propan-1-one

참여 물질

반응 단계

To a stirred solution of 1-(3-nitrophenyl)propan-1-one (1.41 g, 7.90 mmol) in acetic acid (20 mL) was added bromine dropwise (1.27 g, 7.93 mmol) and the mixture was stirred at room temperature for 24 h. The mixture was poured into ice-cold water and the organic layer was extracted with DCM. The organic extract was washed with sat. aq. NaHCO3 and brine, dried over anhydrous MgSO4, and filtered. Evaporation of the solvent under reduced pressure afforded 11z as a white solid which was used in the next step without further purification (1.78 g, 87%). 1H NMR matches literature data.
