Synthesis. Developments in medicine follows advances in synthetic chemistry. Anyone that disagrees would perhaps be well served to imagine the state of surgery if organic chemists had not developed local anesthetics. The following structure is the free base of hexylcaine (1), a local anesthetic developed by Merck. Propose a synthesis of 1 starting (1) from benzene and acyclic components containing five carbons or less. Justify any chemo-, regio- or stereo selective steps in your synthesis. (
