4. Propose an efficient synthesis of the molecule below starting with benzene. You can use any other reagents you want. NOTE: Some reactions produce ortho- and para-products. It is allowable to just take ONE of the products and use it in the next synthesis or claim it as the final product (we assume that ortho- and para-products can be separated). (3 points) CH2CH2CH Br
