Sodium Iodide → N-[3-[2-[2-(2-Ethoxyethoxy)ethoxy]ethoxy]-5-[(12-phenoxydodecyl)oxy]phenyl]-N-(2-methoxy-2-oxoethyl)glycine methyl ester

Participants

Reaction Steps

A mixture of 1.2 g (2.27 mmol) of N-[3-hydroxy-5[(12-phenoxydodecyl)oxy]phenyl]-N-(2-methoxy-2-oxoethyl)glycine methyl ester, 2.73 g (11.37 mmol) of 2-[2-(2-ethoxyethoxy)ethoxy]ethyl bromide, 0.94 g (6.8 mmol) of potassium carbonate and 1.0 g (6.8 mmol) of sodium iodide in 40 ml of acetone and 20 ml of DMF was stirred at reflux under argon for 64 hours. After the usual workup the product was purified by HPLC using 40% ethyl acetate-hexane to give 1.16 g (74% yield), mp<24°, of N-[3-[2-[2-(2-ethoxyethoxy)ethoxy]ethoxy]-4-[(12-phenoxydodecyl)oxy]phenyl]-N-(2-methoxy-2-oxoethyl)glycine methyl ester.
