Procedure
To 566 mg (0.553 mmol) of 2-[tris(oleoyloxymethyl) methylamino]-1-ethanesulfonic acid in 10 mL THF was added 410 mg (4.06 mmol) of triethylamine. After 5 min 96 mg (0.960 mmol) of succinic anhydride was added. The yellow solution was stirred for 18 h under reflux. The solvent was removed under reduced pressure. The residual oil was purified by chromatography on silica gel, eluted with an ethyl acetate/methanol gradient (25:75 vol/vol to 0:100 vol/vol). N-[tris(oleoyloxymethyl)methyl]-N-(2-sulfoethyl) succinic acid monoamide was isolated as a yellow heavy viscous oil with a yield of 240 mg (38%).
