A mixture of hydrobromic acid (50 ml, 46% w/v) and 1-(2-hydroxyethyl)naphthalene (10.0 g, 0.058 mol) was stirred and heated under reflux for 4 h. After cooling, the reaction mixture was diluted with water (150 ml), and the resulting precipitate was extracted with ether (3×150 ml). The ether extracts were combined and dried (MgSO4), when the ether was evaporated under reduced pressure, to afford 1-(2-bromoethyl)-naphthalene which was used without further purification.
