Hofmann bromamide reaction : this method is used for the preparation of any $1^{\circ}$ amine as well as aniline. During the reaction amide is treated with $Br _{2}$ and alkali $(KOH)$ to get primary amine. This reaction is used to descend the series in which carbon atom is removed as carbonate ion $\left( CO _{3}^{2-}\right)$ reaction is given as
