Versuchsvorschrift

The phenol was dissolved in DMF (5 mL) at room temperature. Sodium hydride (60% in oil) was added and the mixture allowed to stir 30 min. 4-Bromomethyl-pyridine was added and the reaction was allowed to stir over night. Ethanol was added and the reaction was concentrated in vacuo. The residue was partitioned between ethyl acetate and water, then extracted three times with ethyl acetate, dried over MgSO4, filtered and concentrated down. The crude residue was purified by silica gel chromatography (2/98 methanol/dichloromethane-5/95 methanol/dichloromethane gradient) to afford the product.
