Which of the following amines can be prepared from a suitable alkyl halide by the Gabriel phthalimide synthesis (potassium phthalimide, then hydrolysis or hydrazinolysis)?

The method works for primary alkyl halides (SN2): propyl halide gives propylamine and benzyl halide gives benzylamine. Aniline would need an aryl halide, which does not react. The tert-butyl halide undergoes elimination instead of SN2, so tert-butylamine is not obtained.
