Stearoyl chloride → HCID 88120683, compound

Participants

Reaction Steps

Stearoyl chloride (5.45 g; 18 mmol) dissolved in CHCl3 (60 mL) was added dropwise in 1 h to a solution of N2,N2-bis[2-[bis[2-(1,1-dimethylethoxy)-2-oxoethyl]amino]ethyl]-L-lysine 1,1-dimethylethyl ester (13.5 g; 18 mmol) in CHCl3 (300 mL) at 0° C. After 10 min the reaction mixture was allowed to rise to room temperature and TLC analysis showed the complete conversion of the starting materials. The solution was washed with 5% aq. NaHCO3, the organic phase was separated, dried over Na2SO4 and then evaporated under reduced pressure. The crude product was purified by flash chromatography (n-hexane/EtOAc=6/4 (v/v)) to give the desired product (11.3 g; 11.2 mmol). Yield 62%. HPLC: 95% (area %). the 13C-NMR, MS and IR spectra were consistent with the structure.
