실험 절차

Stearoyl chloride (6.4 g; 21 mmol) (commercial product) was added dropwise in 5 min to a solution of 2-(2-aminoethoxy)ethanol hydrochloride (2.9 g; 20 mmol) in DMF (50 mL) at room temperature to afford a suspension. After 16 h, the suspension was diluted with acetone and the precipitated solid filtered and washed with acetone. The crude was crystallized from EtOAc; the solid was filtered, washed with EtOAc and dried under reduced pressure to give the desired compound (3.3 g; 8 mmol). Yield 40%. Acidic titer (0.1 N NaOH): 93%. K.F.: 1.06%. The 1H-NMR, 13C-NMR, MS and IR spectra were consistent with the structure.
