Procedure

A mixture of 4-(tert-butyl)benzyl bromide (6.252 g, 27.522 mmol), 4-bromo-2-nitrophenol (5.0 g, 22.934 mmol), potassium carbonate (12.679 g, 91.736 mmol) and dimethylformamide (40 ml) was stirred at 50° for 3 hours under argon atmosphere. The reaction mixture was cooled to room temperature, diluted with water and extracted with ethyl acetate. The organic layer was washed with water and saturated brine, and dried over anhydrous sodium sulfate. The residue obtained by evaporation of the solvent under reduced pressure was washed with n-hexane to give the title compound (8.1 g, 97.0%) as a white solid.
