Versuchsvorschrift

5-Bromo-2-hydroxybenzylalcohol (5.0 g, 24.6 mmol), ethyl iodide (11.5 g, 73.8 mmol) and K2CO3 (3.4 g, 24.6 mmol) in 50 ml of acetone was stirred at +50° C. overnight. The mixture was filtered and evaporated. The product was purified by silica gel column chromatography (EtOAc/petroleum ether 30:100) to give 5-bromo-2-ethoxybenzyl alcohol.
