**Reaction Problem:**

**Task:** Draw the major product of this reaction. Ignore inorganic byproducts.

**Given Structure:**

- **Reactant:** An acyl chloride compound. The structure contains a carbonyl group (C=O) with a chlorine (Cl) atom attached to the carbonyl carbon.

**Reagents:**

1. **(CH₃)₂CuLi (excess):** This reagent is a Gilman reagent, commonly used for nucleophilic substitution reactions.
2. **H₂O:** Water is used in the second step to quench the reaction.

**Instructions for Drawing the Product:**

- The arrow indicates that the reaction proceeds from the acyl chloride reactant to the final product, which needs to be drawn in the space provided (dashed box labeled "Drawing").

**Explanation of Reaction Mechanism:**

- The Gilman reagent, in excess, will replace the chlorine atom with a methyl group (–CH₃), resulting in a ketone as the major product.
- This is a typical conversion of an acyl chloride to a ketone using an organocuprate reagent.

By utilizing these reagents, the transformation focuses on replacing the leaving group (Cl) while stabilizing the carbonyl center, ultimately forming a more stable compound (ketone) with a methyl substituent.
