Reaction Steps

3-Ethylamino-4-nitro-benzonitrile (0.3 g) was diluted with ethanol (5 mL) and was treated with 10% palladium on carbon (Pd/C)(0.070 g). The mixture was then shaken in a hydrogenation shaker under an atmosphere of hydrogen (40 psi) for 30 minutes. The resulting mixture was filtered through diatomaceous earth and concentrated. Silica gel chromatography using 20% ethyl acetate in hexanes as eluent gave 4-amino-3-ethylamino-benzonitrile (0.08 g).
