N-Benzyl-3-furylmethylamine (12 g, 64 mmol), triethylamine (18 ml, 130 mmol) and 2-bromoethanol (8.0 g, 64 mmol) were stirred at 60° C. to 70° C. for 16 hours in anhydrous N,N-dimethylformamide (120 ml). The reaction solution was mixed with ethyl acetate, washed with water and saturated brine and then dried with anhydrous magnesium sulfate. The solvent was removed by evaporation from the organic layer under a reduced pressure, and the thus obtained material was separated and purified by a silica gel column chromatography to obtain 7.1 g (31 mmol, 48% in yield) of the title compound.
