Sodium Hydroxide → N-(Carboxymethyl)-N-[2-[2-[2-(2-ethoxyethoxy)ethoxy]ethoxy]-5-[(12-phenoxydodecyl)oxy]phenyl]glycine

Participants

Reaction Steps

A solution of 1.15 g (1.67 mmol) of N-[3-[2-[2-(2-ethoxyethoxy)ethoxy]ethoxy]-5-[(12-phenoxydodecyl)oxy]phenyl]-N-(2-methoxy-2-oxoethyl)glycine methyl ester and 1.4 ml (8.4 mmol) of 6 N NaOH in 50 ml of methanol and 10 ml of dioxane was stirred at reflux under argon for 19 hours. After the usual workup the product was crystallized from acetone-hexane to give 0.94 g (85% yield), mp 58°-61°, of N-(carboxymethyl)-N-[3-[2-[2-(2-ethoxyethoxy)-ethoxy]ethoxy]-5-[(12-phenoxydodecyl)oxy]phenyl]glycine.
