실험 절차

A reactor was charged with acetic acid (8.7 L), followed by N-(4-tert-butylphenyl) acetamide (Preparation 110, 6.0 kg, 31.4 mol), The mixture was stirred for ten minutes, followed by the addition of acetic anhydride (6.47 kg, 63.4 mol) slowly at room temperature. The reaction was stirred for fifteen minutes. A solution of fuming nitric acid (3.56 kg, 56.5 mol) in acetic acid (2.1 L) was added slowly at 20-25° C., and stirred at that temperature for another 2 hours. The reaction mixture was added to ice water (42 L) at 10-15° C. and the mixture stirred for one hour. The resulting solids were collected by filtration, washed with water (17 L) and dried at 65-70° C. to provide 7.1 kg of the title compound.
