Question
**Title: Claisen Condensation Reaction of Esters**

**Description:**

This content focuses on the Claisen condensation reaction involving two molecules of a specific ester. The product, derived from the reaction, excludes any inorganic byproducts.

**Reactant Structure:**

The ester reactant displayed is phenyl acetate, characterized by:
- A benzene ring attached to a two-carbon chain ending in an ester group (ethanoate or acetate).
- Molecular formula: C9H10O2.

**Reaction Conditions:**

1. **Base Catalyst**:
   - Sodium methoxide (NaOCH₃) in methanol (CH₃OH).
   
2. **Acidic Workup**:
   - An acidic workup is performed after the initial reaction to neutralize the reaction mixture and stabilize the product.

**Diagram Explanation:**

- Arrow pointing down from the reactant structure signifies the chemical transformation process facilitated by the reagents.
- A two-step process is described: base treatment followed by acidic workup.
- Red-dashed box labeled "Drawing" indicates the area where the structure of the major product should be drawn.
  
**Note**: The major product of the Claisen condensation will typically have a β-keto ester structure.
