Procedure

N,N'-Bis[3-(ethylamino)propyl]-1,7-heptanediamine Treat 3,7,15,19-tetra(t-butoxycarbonyl)-3,7,15,19-tetraazaheneicosane (1.68 gm, 0.0024 mol) with HCl in methanol (50 ml, 1.0N) and stir overnight. Filter the mixture and recrystallize the title compound from methanol/water (20:80, v/v) to yield 0.5 gm of the title compound. Rf is 0.39 on silica gel plates eluted with 40% ammonia (concentrated) in methanol; mp 322-23° C. with degradation.
