Versuchsvorschrift

3-Hydroxybenzaldehyde (3.0 g, 24.6 mmol), ethyl iodide (5.9 ml, 73.8 mmol) and K2CO3 (3.4 g, 24.6 mmol) in 50 ml of acetone was stirred at +40° C. for 6 h and at RT overnight. The mixture was filtered and evaporated. The product was purified by silica gel column chromatography (EtOAc/petroleum ether 15:100) to give 3-ethoxybenzaldehyde.
