Reaction Steps
25.6 g (0.0891 mol) of N-[4-(4-nitrophenylamino)butyl]methanesulfonamide (26) were hydrogenated in a mixture of 49 g of zinc powder, 1.6 g of ammonium chloride, 24 mL of water, and 135 mL of ethanol brought to reflux. After suction-filtering of the slurry, the para-phenylenediamine was isolated in the form of a sulfate by addition of 8.1 mL of 96% sulfuric acid. After filtration and drying, 31.3 g of grey product were obtained.
