Question
**Organic Chemistry Reaction Problem**

**Task:** Determine the major organic product for the reaction scheme shown.

**Starting Material:**
- The starting compound is a brominated compound with an isopropyl group attached to a benzene ring, represented as Br-C6H4-C(CH3)2.

**Reaction Scheme:**
1. The compound is treated with 2 equivalents of Lithium (Li) in diethyl ether (Et2O).
2. Then, 0.5 equivalents of Copper(I) iodide (CuI) are added.
3. Finally, the compound is reacted with 1-bromopropane (CH3(CH2)2Br).

**Instructions:** 
If no reaction occurs, draw the starting material.

**Note:** The given structure on the right shows the starting material with the bromine atom still attached to the benzene ring, indicating an "Incorrect" answer.

The problem requires determining the correct product formed after the sequence of reactions, taking into account organometallic and coupling reactions typically involved in such schemes.
