Reaction Steps
To a solution of 1-fluoro-3-methyl-2-nitro-benzene (5 g, 32.24 mmol, 1.0 eq) in TFA (25 mL) and conc.H2SO4 (10 mL) at 0° C. was added NBS (6.31 g, 35.46 mmol, 1.1 eq) in portions. After addition, the mixture was stirred at room temperature for 2 h. The resulting mixture was poured onto ice and the precipitate that formed collected by filtration, washed with water and dried in vacuo to give the title compound as a yellow solid (5 g, 67%).
