Reaction Steps
A solution of N-cyclopropyl-2-nitro-benzenesulfonamide (7.9 g, 33.0 mmol) in EtOH (50 ml) was treated with HCl (3.0 ml, 4.0 N in dioxane), Pd/C (10%, 100 mg) and shaken in a Parr Hydrogenator at 50 psi for 48 h. The catalyst was removed by filtration and the solvent evaporated to give 6.9 g (84%) of 2-Amino-N-cyclopropyl-benzenesulfonamide as a light grey solid.
