In a manner similar to that of Example 22, methylation of N,N'-(1,6-hexylene)-bis[2-hydroxynonylamine] (36 g.) and treatment of the resulting product (25 g., b.p. 172°-176° C./0.05 mm.) with hydrogen bromide gave N,N'-(1,6-hexylene)-bis-[N-methyl-2-hydroxynonylamine] (I: R = CH3 (CH2)6, R' = CH3, X = (CH2)6, Z = H) dihydrobromide (26.3 g., m.p. 176.0°-177.0° C.).
