Steps:
2 Synthesis of 2 - Aminobenzenesulfonamide
A solution of 2-nitrobenzenesulfonamide (compound 2) (80.0 g, 0.58 mol) in methanol at 50 psi in the presence of catalyst Pd / C (10.0 g, 13% w / w) at a mass concentration of 10%2Followed by hydrogenation at 60 ° C overnight. The catalyst was removed by filtration and the filtrate was concentrated to give 60 g of an off-white solid 2-aminobenzenesulfonamide (Compound 3) in a yield of 95%.
