What is the best reagent for converting 2-phenylpropanamide into 1-phenylethanamine?

1. Excess H₂ / Pt

2. NaOH / ${Br}_{2}$

3. NaBH₄ / Methanol

4. LiAlH₄ / Ether

Hint: Hofmann bromamide reaction

The best reagent for converting 2-phenylpropanamide into 1-phenylethanamine is by NaOH / Br₂ and chemical transformation can be done as follows:

This occurs due to intramolecular migration of alkyl group. It is an example of Hofmann bromamide reaction.
