N-Acetyl-4-aminobiphenyl → Acetamide, N-(3-nitro(1,1'-biphenyl)-4-yl)-

Participants

Reaction Steps

4-Acetaminobiphenyl (17 g, 80.57 mmol)in glacial acetic acid (600 ml) was added a solution of potassium nitrate (18 g, 178 mmol) in conc. sulphuric acid (75 ml) at such a rate that the temperature was kept below 30° C. Following the addition the mixture was stirred at ambient temperature for 72 hours. The reaction mixture was poured into ice-water (1200 ml). The product was filtered off, washed thoroughly with water and dried. Recrystallization from EtOH (99%, 150 ml) afforded 4-acetamino-3-nitrobiphenyl (8.7 g).
