### Reaction Problem

**Given Reaction:**

Start with benzoic acid (\( \text{C}_6\text{H}_5\text{COOH} \)).

1. **Reagent 1:** \( \text{SOCl}_2 \) (Thionyl chloride)
2. **Reagent 2:** \( 2 \text{CH}_3\text{NH}_2 \) (Methylamine)

**Steps of Reaction:**

1. **Conversion to Acid Chloride:**
   - Benzoic acid reacts with \( \text{SOCl}_2 \), converting the carboxylic acid group (\(-\text{COOH}\)) into an acyl chloride group (\(-\text{COCl}\)).
   - The product is benzoyl chloride (\( \text{C}_6\text{H}_5\text{COCl} \)).

2. **Formation of an Amide:**
   - Benzoyl chloride reacts with excess methylamine (\( \text{CH}_3\text{NH}_2 \)).
   - The acyl chloride group is converted into an amide group, forming N-methylbenzamide (\( \text{C}_6\text{H}_5\text{CONHCH}_3 \)).

**Expected Product:**

- **N-methylbenzamide** (\( \text{C}_6\text{H}_5\text{CONHCH}_3 \))

This reaction sequence illustrates the transformation of a carboxylic acid to an acyl chloride and then to an amide, a common pathway in organic synthesis for modifying the carboxylic acid functional group.
