step 2—To a solution of (4-nitro-phenyl)-methanesulfonamide (1.18 g, 5.41 mmol) in EtOH (120 mL) was added Pd/C (10%, 118 mg). The mixture was stirred overnight under H2 (balloon pressure), the catalyst was filtered off on a CELITE® pad and the filter cake was washed with EtOH. The filtrate was concentrated in vacuo to afford (4-amino-phenyl)-methanesulfonamide.
