Reaction Steps
A mixture of 3-nitro-4-phenoxy-5-sulfamoylbenzoic acid (3.7 g, 0.011 mol), 10% palladium on carbon (0.5 g) and ethanol (100 ml) is shaken on a Parr hydrogenator for 1.5 hours at a hydrogen pressure of 40 psi. The catalyst is filtered off and the filtrate is concentrated to yield 3-amino-4-phenoxy-5-sulfamoylbenzoic acid (IX-A).
