Show retro-synthetic analysis leading from the target molecule to the precursor molecule showing all intermediate molecules. Using organic chemistry from your textbook show an efficient synthesis of your target molecule starting from its parent molecule and showing the structure of each isolable intermediate. Assume you have access to usual reagents like Br2, AlCl3, Fe, HBr, HNO3, H2SO4, etc. Assume that each intermediate can be purified from other products at each step of the synthesis.
