반응 단계

A 100-ml two-necked flask equipped with a stirrer, dropping funnel and N2 inlet tube was charged with 4.58 g (75 mmol) of ethanolamine and 9.2 g of ethanol. The contents were heated to 80° C. with stirring in an N2 atmosphere, and an ethanol solution of 1.71 g (5 mmol) of 11-(butyldimethylsilyl)undecyl glycidyl ether was added dropwise to the contents over 1 hour. The resultant mixture was stirred further for 1 hour at 80° C. After completion of the reaction, ethanol and excess ethanolamine were distilled off under reduced pressure, and the resultant residue was purified by column chromatography on silica gel, thereby obtaining 1.48 g (yield: 73%) of the title compound (Ia-18).
