実験手順
A mixture of 8.2 g. of 4-nitro-2,6-bis-trifluoromethylaniline, 3.6 g. acetic anhydride, and 20 ml. of pyridine is heated for 48 hours on a steam bath. The reaction mixture is poured onto ice water and the solid material is filtered, dried and recrystallized from isopropanol affording 4-acetylamino-3,5-bis-trifluoromethylnitrobenzene.
