Participants

Reaction Steps

To a solution of 4-hydroxybenzaldehyde (366 mg, 3 mmol) in anhydrous DMF (7 ml), under nitrogen atmosphere, K2CO3 (829 mg, 6 mmol), and, after 10 minutes, bromoethanol (450 mg, 3.6 mmol) were added. The mixture was heated to reflux for 3 hours, then water was added and the product was extracted with CH2Cl2. The organic layers were washed with water and with NaCl saturated solution, dried with Na2SO4. After evaporation of the solvent, the crude product was purified by chromatography on silica gel (Petroleum ether/Ethyl acetate 2/1); 400 mg (yield 80%) of pure product of the title were obtained.
