实验步骤: 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. This reaction mixture was then filtered the filtrate was concentrated under reduced pressure The residue was dissolved in methylene chloride washed with water The washed solution was dried concentrated

实验步骤: In a three-neck flask they are introduced 7.2g 3-diethylaminopropionic acid (hydrochloride) and 180 ml hexamethylphosphorotriamide. The suspension is cooled with an ice-bath and then 2,90 ml thionylchloride are added while maintaining the inner temperature between +5° - +10° C. The reaction mixture progressively gives a yellow solution. After 2 hours stirring 10.9 g of 2-methoxy 5-morpholinylsulphonyl aniline are added portionwise and the whole mixture is kept under stirring for 4 hours at room temperature and then let to stand for a night. The dark solution is thereafter diluted with 1 l ethyl ether and it appears a precipitate. After 1 hour standing the precipitate is collected, suction-filtered and washed with acetone. After thoroughly drying the raw product weighing 11.3g is recovered and further recrystallised from acetone.
