실험 절차

In 6 ml of methylene chloride-N,N-dimethylformamide (1:2) was dissolved 120 mg (0.20 mmol) of 1,2-O-dioleylglycerol, followed by addition of 168 mg (1 mmol) of 4-dimethylaminobutyric acid hydrochloride. Then, 206 mg (1 mmol) of N,N'-dicyclohexylcarbodiimide (DCC) and 25 mg (0.2 mmol) of 4-dimethylaminopyridine were further added and the reaction was conducted at ambient temperature overnight. The precipitated byproduct urea was filtered off using a glass filter and the filtrate was concentrated to dryness under reduced pressure and treated with methylene chloride-saturated aqueous sodium hydrogen carbonate solution. After phase separation, the methylene chloride layer was dried over sodium sulfate and the solvent was distilled off under reduced pressure. The residue was subjected to column chromatography (silica gel/methylene chloride-methanol) to provide 123 mg (87%) of the title compound.
