实验过程
A 500-ml flask equipped with a stirrer and reflux condenser was charged with 3.01 g (79.3 mmol) of LiAlH4 and 200 ml of tetrahydrofuran. While stirring the mixture at room temperature in an N2 atmosphere, 5.00 g (13.9 mmol) of N,N-bis(2-hydroxyethyl)-16-hydroxyhexadecanamide were added, followed by stirring at 65° C. for 18 hours. After cooling the reaction mixture to room temperature, 15 g of 3% aqueous KOH were added, and a salt deposited was separated by filtration. The solvent was then distilled off under reduced pressure, and the resultant residue was purified by column chromatography on silica gel, thereby obtaining 2.98 g (yield: 62%) of the title compound (IId-3).
