Hoffman's degradation is related to the conversion of

Hoffmann Bromamide reaction, also known as Hoffman's degradation reaction is a reaction used for the conversion of a primary amide to a primary amine with one less carbon atom.

${\mathrm{CH}}_3{\mathrm{CONH}}_2+4\mathrm{KOH}+{\mathrm{Br}}_2\to {\mathrm{CH}}_3{\mathrm{NH}}_2+{\mathrm{Na}}_2{\mathrm{CO}}_3+2\mathrm{KBr}+2{\mathrm{H}}_2\mathrm{O}$

Thus, it is used in the conversion of amide to amine.
