실험 절차
4.0 g of bromine in 7.3 mL of AcOH was added dropwise to a solution of 4.0 g of 2-nitro-4-trifluoromethyl-phenol and 300 mg FeCl3 in 23.1 mL of AcOH at 0° C. Reaction was then heated at 40° C. for 1.5 h. and then allowed to stir for 65 h at rt. Solvent was then removed, placed solid back into EtOAc, filtered through celite and concentrated in vacuo. 5 g of title compound was collected.
