Reaction Steps

The monosodium salt of 3-hydroxy-5-bromophenol (0.05 mole) and dimethylformamide (75 ml) are charged under nitrogen gas into a glass reaction vessel equipped with a mechanical stirrer, thermometer and additional funnel. The mixture is stirred until dissolved, and 1-chloro-2,2-dimethoxyethane (0.05 mole) is added dropwise over a period of about 20 minutes. After the addition is completed, the reaction mixture is heated at about 90° C. with stirring for a period of about 48 hours. After this time water (200 ml) is added, and the reaction mixture is neutralized with ammonium chloride. The reaction mixture is then extracted with chloroform, and the organic phase is separated from the aqueous phase. The organic phase is then stripped of solvent, leaving an oil. This oil is distilled under reduced pressure to yield the desired product 3-(2,2-dimethoxyethoxy)-5-bromophenol.
