実験手順
A 100-ml flask equipped with a stirrer and dropping funnel was then charged with 16.8 g (280 mmol) of ethanolamine and 15 g of ethanol. While stirring the mixture at 80° C., an ethanol solution of 5.00 g (17.6 mmol) of 1,2-epoxy-2-methyl-3-tetradecyloxypropane was added dropwise over 3 hours. The contents were stirred further for 2 hours. The resultant reaction mixture was concentrated under reduced pressure, and the resultant residue was purified by column chromatography on silica gel, thereby obtaining 4.13 g (yield: 68%) of the title compound.
