Aniline is treated with $CH X_{3} COCl$ in pyridine to give A, A is brominated with $Br X_{2}$ in ethanoic acid to give B (major monobromo product), and B is hydrolysed with aqueous acid and heat to give C. C is

Acetylation gives acetanilide, which reduces the activating power of nitrogen and prevents polybromination. Bromination is mainly para to the

- NHCOCH X_{3}

group. Acid hydrolysis removes the acetyl group to give 4-bromoaniline.
