Reaction Steps

To a solution of 2-hydroxy-3-nitro-6-chlorobenzenesulfonamide (1.1 g, 4.36 mmol) in ethyl acetate, was added 10% Pd/C (500 mg). The mixture was flushed with hydrogen, and then stirred under a hydrogen atmosphere at balloon pressure for 4 hours at room temperature. The mixture was filtered through celite and the celite was washed with methanol. The solvent was evaporated to give the desired product (91%). EI-MS (m/z) 221.1, 223.1 (M).
