反応手順
Twenty-three grams (0.1 mole) of 4-acetamidobenzophenone, 50 ml. of acetic anhydride and 20 ml. of acetic acid were stirred together. A solution of 90 percent nitric acid (15 ml.), 10 ml. of acetic acid and 0.2 g. of urea was added dropwise to the benzophenone mixture. The reaction mixture was maintained at a temperature of about 50° C. during the nitration. The mixture was stirred at ambient temperature whereupon the mixture became very thick. The thick slurry was poured over ice and the insoluble product was filtered to yield 17.7 g. (62.5 percent yield) of 4-acetamido-3-nitrobenzophenone.
