3,5-Dibromophenol (59.6 mmol; 15 g) and imidazole (65.5 mmol; 4.5 g) were dissolved in dichloromethane (150 mL) and tert-butyl-dimethylsilylchloride (65.5 mmol; 9.9 g) was added. The reaction mixture was stirred at room temperature for 16 hours, diluted with diethyl ether, and filtered. The organic solution was washed with saturated ammonium chloride, saturated sodium hydrogen carbonate, and water and dried and evaporated to dryness. Yield: 22 g. HPLC-MS: m/z: 366.9 (M+); Rt: 3.09 min.
