Iron powder (0.15 g, 2.574 mmol) was added to a solution of dimethyl-(4-nitro-2-oxazol-2-yl-phenyl)-amine (200 mg, 0.86 mmol) in acetic acid (3 ml) and stirred overnight at room temperature. The reaction mixture was poured into ice water and basified with dilute sodium hydroxide solution and then filtered. The filtrate was extracted with ethyl acetate, and the organic layer was washed with water, then brine and dried. Evaporation to dryness gave N1,N1-dimethyl-2-oxazol-2-yl-benzene-1,4-diamine (150 mg, 88.2%) as oil.
