1. Preparation of propan -1- amine from butane nitrile.
Butane nitrile treated with acid hydrolysis followed by Hoffmann’s bromamide degradation. gives propan – 1 – amine.
2. Preparation of propan – 1 – amine from propanamide.
When propanamide is treated with LiAIH in the presence of water gives propan – 1 – amine.
3. Preparation of propan – 1 – amine from 1 – nitropropane.
Reduction of 1 – Nitropropane using H2 / Ni or Fe / HCl gives propan – 1 – amine.
