反応手順
4.4 g of 2-hydroxyphenethyl alcohol was dissolved in 80 ml of N,N-dimethylformamide, and 15.3 g of ethyl iodide and 4.7 g of potassium carbonate were added. After stirring was continued at 70° C. overnight, the solution was diluted with ethyl acetate, and washed successively with water and saturated brine. The organic layer was dried over anhydrous magnesium sulfate, and then the solvent was evaporated. The residue was purified by silica gel column chromatography, to give 3.2 g of the title compound in the 4:1 hexane-ethyl acetate fraction.
