Reaktionsschritte

6.03 g of the hydrochloride was suspended into 100 ml of acetonitrile, to which 4.79 g of 2-(3,4-dimethoxyphenyl) ethyl chloride, 8.24 g of anhydrous potassium carbonate and n-tetrabutyl ammonium iodide (catalytic amount) were added and refluxed under heating for 20 hours. After allowing them to cool, the inorganic salts were filtered out and the solvent was distilled off. After adding ethyl acetate and washed with water, they were dried with anhydrous magnesium sulfate. The solvent was concentrated and purified on silica gel chromatography to obtain 1.03 g of the above-captioned compound (total yield: 6.5%).
