4-Bromophenol → 1-Bromo-4-(methoxymethoxy)benzene

To a solution of 4-bromophenol (1.0 g, 5.8 mmol) in anhydrous THF (10 mL) was added NaH (60%, 254 mg, 6.4 mmol) at 0° C. After being stirred at the temperature for 0.5 h, MOM-Cl (698 mg, 8.7 mmol) was added to the mixture. The mixture was stirred at 0° C. for 0.5 h, warmed to room temperature for 2 h, quenched with water, and extracted with EtOAc. The organic layer was dried over Na2SO4, concentrated in vacuo, and purified by column chromatography (PE:EtOAc=50:1) to give 1-bromo-4-(methoxymethoxy)benzene (1 g, yield 80%).
