실험 절차

2,5-dibromonitrobenzene (12.0 g, 42.7 mmol) was dissolved in dimethylformamide (DMF, 80 ml), Cu (6.0 g, 93.94 mmol) was added thereto, and then the reaction mixture was reacted at 120° C. for 3 hours. The reaction mixture was cooled to room temperature, the insoluble material was filtered off and the filtrate was concentrated. The resultant product was recrystallized in ethanol to obtain 4,4′-dibromo-2,2′-dinitrobiphenyl (10.2 g, 60%). MS [M+] 354.
