Problem- Why is it important to have methods like Gabriel synthesis, reduction of nitriles, reduction of amides and reductive amination to make specific primary, secondary and tertiary amines; that is why can't we just use Sn2 reactions to make these compounds?
I am not able to get the correct answer please help me
