Reaction Steps

5.0 g (33 mmol) of N-methyl-2-nitroaniline and 5.9 g (33 mmol) of N-bromosuccinimide were added with 60 mL of acetic acid, and the whole was refluxed under heating for 7 hours. After the completion of the reaction, the reaction solution was poured into 500 mL of water, and the precipitated solid was filtered out. The solid that had been filtered out was dissolved into ethyl acetate and dried with magnesium sulfate. After filtration, the solvent was distilled off under reduced pressure, and the residue was dried at room temperature under reduced pressure to obtain 7.1 g of the orange solid of 4-bromo-N-methyl-2-nitroaniline (93% yield).
