Nitration of benzene followed by reduction with $Sn$ and concentrated $HCl$
Degradation of benzamide with bromine in an alkaline solution
Reduction of nitrobenzene with $H_2$/$Pd$ in ethanol
Potassium salt of phthalimide treated with chlorobenzene followed by hydrolysis with aqueous $NaOH$ solution
