To a solution of 3-bromophenol (27.4 g, 158 mmol) in CH2Cl2 was added chloromethyl methyl ether (18 mL, 237 mmol). The reaction mixture was cooled to 0° C. and diisopropylethylamine (55 mL, 316 mmol) was added and the cold bath was removed. The reaction mixture was stirred for 3 hours at ambient temperature and then poured into 10% aqueous HCl. The layers were separated and the aqueous phase was extracted 4 times with CH2Cl2. The combined organic layers were washed once each with saturated aqueous NaHCO3, 15% aqueous NaOH, and brine, dried over MgSO4, filtered, and concentrated in vacuo to provide 3-methyloxymethoxy-bromobenzene as a yellow oil.
