Versuchsvorschrift

To a suspension of 1.00 g (7.24 mmol) of 2-hydroxyphenethyl alcohol and 1.35 g (8.68 mmol) of potassium carbonate in 15 ml of N,N-dimethylformamide was added 2.00 g (14.48 mmol) of iodoethane at 0° C. The reaction mixture was stirred at 40-45° C. for 12 h and was poured into 200 ml of ether. It was washed with water (20 ml ×3), dried over MgSO4 and concentrated. The residue was purified by silica gel chromatography with 9:1 hexane/ethyl acetate to afford the 2-ethoxyphenethyl alcohol as a colorless oil.
