Synthesize the product with benzene as the starting material (clickthe link below to see the problem)
http://i.imgur.com/TUUVv.png
For the first problem, I start out by doing nitration on thebenzene then do bromination and finally convert the NO2 group intoNH2 group with Sn/HCl but I'm not sure if the whole synthesis iscorrect and if the reagent that I need to convert NO2 group intoNH2 group is correct.
For the 2nd problem, I start out by doing brominationfirst-->add SO3H in the ortho position-->add CH3 in paraposition by using CH3Br in AlCl3-->use dil. acid to get rid ofSO3H-->use NBS in light to add Br in the methyl group. BUT I'mnot sure 1)when to get rid of the SO3H group 2) should I usebromination first or make the benzene become benzyl bromide first.If my way of thinking isn't correct, please help me out :(
