実験手順
A mixture of N-(3,6-dimethyl-2.4-dinitro-phenyl)-acetamide (14.4 g, from above), concentrated sulfuric acid (15 mL), water (30 mL) and ethanol (150 mL) was heated at reflux for 24 hr. The precipitated product was filtered, washed with little ethanol and dried to afford 3,6-dimethyl-2.4-dinitro-phenylamine (10.3 g).
