A solution of N,N'-(1,6-hexylene-bis[2-hydroxyundecylamine] (5 g.), glycolic acid (1.66 g.) and methanol was heated until the solids dissolved, then evaporated to dryness. Recrystallization of the solid from acetone afforded N,N'-(1,6-hexylene)-bis[2-hydroxyundecylamine] diglycolate (4.6 g., m.p. 88.2°-94.6° C.). In a similar manner using acetic acid and lactic acid instead of glycolic acid there were obtained, respectively, N,N'-(1,6-hexylene)-bis[2-hydroxyundecylamine] diacetate (m.p. 113°-120.6° C.) and N,N'-(1,6-hexylene)-bis[2-hydroxyundecylamine] dilactate (m.p. 102.0°-104.0° C.).
