Procedure:
To a solution of benzotriazole (3 g) in DMF (38 mL) at r.t. was added a solution of 10N NaOH (2.75 mL). After stirring for 25 min., 3-trifluoromethylbenzyl bromide (4.39 mL) was added. The mixture was further stirred for 30 min., diluted with H2O, and extracted with EtOAc. The EtOAc extract was washed brine (2×), water, brine, dried (MgSO4) and concentrated. The residue was stirred in diethyl ether/hexane to afford 3.96 g of the title compound as a white solid.

The mixture was heated to reflux and hydrobromic acid (48%; 16.7 mL; 147 mmol) was added dropwise over a period of 20 min. Upon completion of the addition, the reflux was maintained an additional 15 min. The reaction was cooled to 0° C. (ice bath), and sodium nitrite (2.23 g; 32.3 mmol) in H2O (20 mL) was added over a period of 30 min. The stirring was continued for 15 min. at 0° C., the mixture transferred to a jacketed dropping funnel (0° C.) and added dropwise to a stirred mixture of Cu(I)Br (5.34 g; 37.2 mmol) in H2O (29.5 mL) and HBr (48%; 16.7 mL; 147 mmol) at 0° C. The reaction was stirred for 15 min. at 0° C., warmed to 60° C., stirred for an additional 15 min., cooled to room temperature, and left to stir overnight. The reaction mixture was transferred to a separatory funnel and extracted with ether (3×150 mL). The organic layers were combined, washed with brine (1×), dried (Na2SO4), filtered and concentrated to afford the crude product (7.99 g) as a red-brown oil. The crude material was purified by flash column chromatography (1:25 ultra pure silica gel, 230-400 mesh, 40-60 mm, 60 angstroms; CH2Cl2 as the solvent) to afford pure 2-bromo-3-nitrophenol 1b2 (45%; 3.16 g) as an orange-brown solid.
