Procedure

In a sealed system, ((2-((2-(dimethylamino)ethyl)thio)acetyl)azanediyl)bis(ethane-2,1-diyl) ditetradecanoate (1.00 g, 1.49 mmol) was combined with 2-bromoethanol (687 uL, 9.69 mmol) was added. The reaction vessel was flushed with inert gas and then sealed. Reaction was heated to 75° C. and allowed to stir overnight, then cooled, and concentrated in vacuo. Purification by silica gel chromatography with DCM/MeOH gradient yielded 2-((2-(bis(2-(tetradecanoyloxy)ethyl)amino)-2-oxoethyl)thio)-N-(2-hydroxyethyl)-N,N-dimethylethanaminium bromide (HES104) (790 mg). LCMS ESI+: m/z 715.7 (M+H).
