실험 절차

A solution of 16 g. of 11-bromoundecanol, 9.9 g. of ethyl 4-aminobenzoate, and 6.0 g. of triethylamine in 50 ml. of hexamethylphosphoramide is stirred at 70° C. under argon for 128 hours. The resulting solution is cooled, diluted with water, and filtered. Recrystallization of the solid from acetonitrile affords ethyl 4-(11-hydroxyundecylamino)benzoate as a white, crystalline solid.
