The most convenient method to prepare an amine containing one carbon atom less is
A.
Gabriel phthalimide synthesis
B.
reductive amination of aldehydes
C.
Hofmann bromamide reaction
D.
reduction of isonitriles
Answer :
Hofmann bromamide reaction
Solution :
Hoffmann bromamide reaction is the best method to reduce one carbon atom in the amine from amide.
$$C{H_3}C{H_2}CON{H_2} + B{r_2} + 4KOH$$ \[\xrightarrow{\text{heat}}C{{H}_{3}}C{{H}_{2}}N{{H}_{2}}+2KBr\] $$ + {K_2}C{O_3} + 2{H_2}O$$
