Conversion of Aniline to p-bromoaniline

Explanation

To convert aniline to p-bromoaniline, we can follow these steps:

### Step 1: Acetylation of Aniline
- Start with aniline (C6H5NH2).
- Treat aniline with acetic anhydride or acetyl chloride in the presence of pyridine. This will lead to the formation of acetanilide (C6H5NHCOCH3).

**Reaction:**
\[ \text{C}_6\text{H}_5\text{NH}_2 + \text{(CH}_3\text{CO})_2\text{O} \rightarrow \text{C}_6\text{H}_5\text{NHCOCH}_3 + \text{CH}_3\text{COOH} \]
