Versuchsvorschrift

The reaction mixture of 2-(2-hydroxy-ethylamino)ethanol (32 g, 310 mmol), 1-(2-bromoethoxy)benzene (51 g, 256 mmol), and potassium carbonate (70 g, 512 mmol) in ethanol (200 mL) was refluxed overnight, concentrated, and partitioned between water and ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate, and concentrated. The residue was purified by column chromatography to afford the title compound (45 g, 78%).
