Prepare pure sample of `1^(@) ` amine from `1^(@)` alkyl halide.

Explanation

To prepare a pure sample of 1° amine from a 1° alkyl halide, we can use the Gabriel Thalamide Synthesis method. Here’s a step-by-step breakdown of the process:

### Step 1: Prepare Thalamide
- Start with thalamide, which has the structure of a benzene ring with a carbonyl group (C=O) and an amine group (NH).
- The structure can be represented as:
\[ \text{C}_6\text{H}_5\text{C(O)NH} \]
