Participants

Reaction Steps

To N1,N1′-((5-(3-(iso-Butylamino)propoxy)-1,3-phenylene)bis(methylene))bis(N3-(3-aminopropyl)propane-1,3-diamine) from step 6 was added methanolic HCl (50 mL, 1.0M). The reaction mixture was stirred for 1 h, the reaction mixture was concentrated under reduced pressure and the solid collected by vacuum filtration. The solid was washed with Et2O (10 mL) and hot MeOH (10 mL) to afford the desired product (0.14 g, 43%) as a white solid. 1H NMR (500 MHz, D2O) δ ppm 7.21 (s, 1H), 7.19 (s, 2H), 4.30 (s, 4H), 4.23 (t, J=5.5 Hz, 2H), 3.29 (t, J=7 Hz, 2H), 3.25-3.19 (m, 12H), 3.12 (t, J=7.5 Hz, 4H), 2.95 (d, J=7 Hz, 2H), 2.25-2.03 (m, 11H), 1.01 (d, J=7.5 Hz, 6H). 13C NMR (125 MHz, D2O) 158.9, 133.0, 123.7, 117.1, 65.8, 54.8, 50.7, 45.7, 44.7, 44.6, 44.2, 36.7, 25.5, 25.2, 23.7, 22.6, 19.1.
