Procedure

In a solvent mixture of 3 ml N,N-dimethylformamide and 6 ml methylene chloride was dissolved 172 mg (0.277 mmol) of 1,3-dioleoylglycerol followed by addition of 101 mg (0.556 mmol) of N,N-diethyl-β-alanine (hydrochloride), 114 mg (0.553 mmol) of N,N-dicyclohexylcarbodiimide, and 7 mg (0.057 mmol) of 4-dimethylaminopyridine and the mixture was stirred overnight. This reaction mixture was then filtered and the filtrate was concentrated under reduced pressure. The residue was dissolved in methylene chloride and washed with water. The washed solution was dried and concentrated and the residue was subjected to column chromatography (silica gel/methylene chloride-methanol) to provide 129 mg (62%) of the title compound of the invention.
