Versuchsvorschrift
The procedure of (2) of Example 1 was repeated with the exception that N,N'-bis(2-aminoethyl)-1,3-propylenediamine was used in place of triethylenetetramine. Thus, 3-(3-cyanopropyl)-2,4-dioxo-1,5,8,12-tetraaza-cyclotetradecane (C-substituted cyclic diamide) was obtained in a yield of 30%.
