$N-$Methylbenzylamine

Vedclass · Answer

(D) Gabriel phthalimide synthesis is used for the preparation of primary aliphatic amines. In this reaction,potassium phthalimide reacts with an alkyl halide to form an $N-$alkyl phthalimide,which is then hydrolyzed to yield the primary amine. This method is not suitable for the preparation of aromatic amines because aryl halides do not undergo nucleophilic substitution with the phthalimide anion. Additionally,it is not suitable for secondary or tertiary amines. Among the given options,$N-$methylbenzylamine is a secondary amine. Since Gabriel synthesis is specifically designed for primary amines,it cannot be used to prepare $N-$methylbenzylamine.

Which of the following amines cannot be prepared by Gabriel phthalimide synthesis?
