Reaction Steps
A mixture of 2.0 g (3.83 mmol) of N-[3-hydroxy-5-(octadecyloxy)phenyl]-N-(2-methoxy-2-oxoethyl)glycine methyl ester, 4.15 g (15.3 mmol) of 2-[2-[2-(2-methoxyethoxy)ethoxy]ethoxy]ethyl bromide, 1.2 g (7.66 mmol) ofsodium iodide and 1.6 g (11.5 mmol) of potassium carbonate in 60 ml of acetone and 30 ml of DMF was stirred at reflux for 48 hours. The solvents were removed at reduced pressure and the residual oil was purified by HPLCusing 60% ethyl acetate-hexane to give 2.01 g (73% yield) of N-[3-[2-[2-[2-(2-methoxyethoxy)ethoxy]ethoxy]ethoxy]-5-(octadecyloxy)phenyl]-N-(2-methoxy-2-oxoethyl)glycine methyl ester. The nmr and mass spectra were consistent with the structure.
