Reaction Steps

To a solution of N1,N1-Dimethyl-N2-(4-nitro-phenyl)-propane-1,2-diamine (446 mg, 2 mmol) in absolute ethanol (20 mL) was added hydrazine monohydrate (0.78 mL, 8 equiv.) followed by the addition of a small portion of Raney nickel. The reaction mixture was heated to 50° C. with stirring for 2 h at which point all gas evolution had ceased. The reaction mixture was filtered through celite to remove the Raney nickel. The filtrate was concentrated under reduced pressure to give the N-(2-Dimethylamino-1-methyl-ethyl)-benzene-1,4-diamine as a brown oil. This material was carried on in subsequent steps without purification.
