why cannot aromatic primary amines be prepared by gabriel pthalimide reaction

In Gabriel phthalimide synthesis, phthalimide reacts with ethanolic potassium hydroxide to form potassium salt of phthalimide.The salt is heated with alkyl halide followed by alkaline hydrolysis to give the corresponding primary amine.Now, aromatic halides do not undergo nucleophilic substitution with the salt formed by phthalimide.Therefore, aromatic amines cannot be prepared by Gabriel phthalimide reaction.
