Aniline is diazotized with $\text{NaNO}_2 + \text{HCl}$ at $273-278\text{ K}$ to form benzenediazonium chloride, which on Sandmeyer reaction with $\text{Cu}_2\text{Cl}_2/\text{HCl}$ gives chlorobenzene:
$\text{C}_6\text{H}_5\text{NH}_2 \xrightarrow{\text{NaNO}_2 + \text{HCl},\ 273-278\text{ K}} \text{C}_6\text{H}_5\text{N}_2^+\text{Cl}^- \xrightarrow{\text{Cu}_2\text{Cl}_2/\text{HCl}} \text{C}_6\text{H}_5\text{Cl} + \text{N}_2$

Wurtz reaction:
$2\text{C}_2\text{H}_5\text{Cl} + 2\text{Na} \xrightarrow{\text{dry ether}} \text{CH}_3\text{CH}_2\text{CH}_2\text{CH}_3 + 2\text{NaCl}$
