Water → ethyl [2-(3-Bromopropyl)phenyl]acetate

Participants

Reaction Steps

To a solution of ethyl [2-(3-hydroxypropyl)phenyl]acetate (44.4 g., 0.20 mole) in ether (300 ml.) is added dropwise during 40 minutes a solution of phosphorus tribromide (20.7 g., 0.075 mole) in ether (100 ml.). The temperature is maintained at 25°-28° C. during this time by means of a cold water bath. The reaction solution is then heated at reflux for 4 hours. It is cooled and poured into iced-water. The ether layer is separated, washed with water, dried over magnesium sulfate, and evaporated in vacuo to yield ethyl [2-(3-Bromopropyl)phenyl]acetate.
