Reaction Steps

To a stirred mixture of iron powder (0.5 g), ethanol (20 ml), water (1 ml) and concentrated hydrochloric acid (5 drops) at reflux was added N,N-Dimethyl-C-(3-nitro-phenyl)-methanesulfonamide (0.5 g). The mixture was then heated under reflux for a further 2 hours then basified with excess sodium carbonate solution, cooled to 60° C., then filtered. The filter cake washed with ethanol and the filtrate evaporated. The crude product was partitioned between ethyl acetate and water, separation and evaporation of the organic phase gave C-(3-Amino-phenyl)-N,N-dimethyl-methanesulfonamide, 0.4 g, sufficiently pure to use.
