Reaction Steps
To a solution of 4-fluoro-2-nitrotoluene (2.0 g) in trifluroacetic acid (8 ml) was added concentrated sulfuric acid (2.5 ml) followed by N-bromosuccinimide (3.4 g). After stirring for 24 hours the reaction mixture was then diluted with ethyl acetate, washed with water, brine, dried (MgSO4) and the solvent removed in vacuo. The residue was purified by flash chromatography to give 1-bromo-5-fluoro-2-methyl-3-nitro-benzene (2.48 g).
