To a 2-l flask equipped with a stirrer, a dropping funnel, a nitrogen gas inlet tube and a distillation apparatus, 611 g (10.0 mol) of 2-aminoethanol (5-a) and 122 g of ethanol were charged, followed by the dropwise addition of 243 g (0.82 mol) of hexadecyl glycidyl ether (4-a) over 3 hours while stirring under heating to 80° C. in a nitrogen gas atmosphere. After the completion of the dropwise addition, stirring was conducted for further 2 hours at 80° C. From the reaction mixture, ethanol and excessive 2-aminoethanol were distilled off by heating under reduced pressure. The residue was purified by chromatography on a silica gel column, whereby 262 g of the title compound (6-t) were obtained in the form of a white solid (yield: 90% relative to hexadecyl glycidyl ether).
