실험 절차

To a mixture of 4-acetamido-1,1′biphenyl (21.1 g, 0.1 mol) and 150 mL of acetic anhydride maintained between 8° C. and 13° C. is slowly added dropwise over 32 minutes 12.7 mL of 70% nitric acid. The reaction mixture is added to 600 mL of a mixture of water and ice and the resultant precipitate is collected by filtration. The filter cake is washed with water and the residue is recrystallized from methanol (800 mL) to give 23.6 g of the title compound as a yellow crystalline solid melting at 129-132° C.
