Problem 3 Propose a synthesis of the following molecule from the given starting material. You may use any reactions we have learned in this course so far, and any reagents containing the carbon atoms you need. If you make a mixture in any of the steps, place a box around the compound you would separate from the mixture, and carry on with your synthesis assuming you can isolate the desired regioisomer. NH2
