Procedure

A solution of 1-bromo-2-(2-hydroxy-ethyl)-naphthalene (46.5 g, 0.185 mol) in methylene chloride (370 mL) was placed under a nitrogen atmosphere, cooled in an ice bath, and stirred. Triethylamine (32.3 mL, 0.232 mol) was added followed by acetyl chloride (15.8 mL, 0.222 mol) dropwise over 5 minutes. The reaction mixture was removed from the ice bath and stirred at room temperature for 15 minutes. The reaction mixture was washed with water (300 mL), 1N hydrochloric acid (200 mL) and water (250 mL), dried over magnesium sulfate, filtered, and evaporated under vacuum to afford the title compound as an oil (55.1 g).
