Cz. Xia et al., A convenient synthesis of N,N,N '-trisubstituted ethylenediamine derivatives from 2-methyl-2-imidazoline, SYN COMMUN, 30(18), 2000, pp. 3307-3315
A series of N, N, N'-trisubstituted ethylenediamine derivatives has been pr
epared from 2-methyl-2-imidazoline by a convenient three-step process in hi
gh yields: sulfonylation, methylation, and reactions with nucleophiles.
