Well, to answer my own question regarding the leaving group, using a Raney catalyst would cleave the methansulfonamide chain at the sulfur atom. Thus, one would be left with a methyl group at the 5 position of the benzene ring. Does anyone know how you could reduce this methyl group? Please, be careful when working with Raney Catlaysts. For those who don't know, Raney catalysts are a Ni/Al complex. They are commercially available in solution. NEVER let the catalyst dry out! If the Raney catalyst dries out it will react violently with O2 in the air (boom).
