実験手順
A mixture of 1-acetamido-2-nitro-3,5-bis(trifluoromethyl)benzene (200 mg, 0.63 mmol) in concentrated HCl (3 mL) and EtOH (3 mL) was refluxed overnight, then it was extracted by ethyl acetate (2×3 mL). The extract was dried over Mg2SO4 and evaporated to give 2-nitro-3,5-bis(trifluoromethyl)aniline 123 mg (71%). 1H NMR (DMSO-d6): δ6.392 (s, 2H), 7.131 (s, 1H), 7.375 (s, 1H).
