Procedimiento

A 100-ml flask equipped with a stirrer and dropping funnel was charged with 23.7 g (250 mmol) of ethanolamine and 23.7 g of ethanol. While stirring the mixture at 80° C., an ethanol solution of 8.20 g (25 mmol) of butyl 12-(2,3-epoxypropoxy)-dodecanate was added dropwise over 1 hour. After completion of the reaction, water was added to the reaction mixture, followed by extraction with chloroform. The resultant chloroform solution was concentrated under reduced pressure, and the resultant residue was purified by column chromatography on silica gel, thereby obtaining 5.40 g (yield: 55.4%) of the title compound (Ia-15).
