Reaction Steps

To a solution of 1-bromo-4-tert-butyldimethylsiloxy-2-methoxymethoxymethylbenzene (34.2 g, 94.8 mmol) in tetrahydrofuran (100 mL) was added tetrabutylammonium fluoride (1 mol/L in tetrahydrofuran, 50 mL), and the mixture was stirred at room temperature for 1 hour. Water was added, and the mixture was extracted with ethyl acetate. The organic layer was washed with brine and dried on anhydrous sodium sulfate. The solvent was removed under reduced pressure, and the residue was purified by silica gel column chromatography (2:1 hexane/ethyl acetate) to give 4-bromo-3-(methoxymethoxymethyl)phenol (25.9 g, quant).
