Reaction Steps
To a solution of triamine F5 (0.22 g, 0.59 mmol) in 1:2 EtOH:H2O (60 mL) were sequentially added 6-dimethylamino-4-chloroquinoline (0.13 g, 0.64 mmol) and c.HCl (0.16 mL, 5.32 mmol), and the resulting solution was refluxed for 20 h (reaction progress followed by TLC, eluting with the top phase of a 5:4:1 mixture of n-BuOH:H2O:acetic acid). After this time, solvent was removed under reduced pressure, and the residue dried via two MeOH-azeotrope cycles. The residue was re-precipitated from MeOH:EtOAc to give Cpd. JJ1 (61 mg, 19%) as an amorphous dark brown solid; mp 239-243° C. (powder-glue), 278-282° C. (glue-liquid); 1H NMR (400 MHz, DMSO): δ 14.44 (s, 1H, quinolinyl-N+—H), 11.20 (s, 1H, hydrazonyl-N+—H), 10.58 (s, 1H, ArC(O)NHAr), 10.46 (s, 1H, ArNHAr), 8.35 (d, J=6.71 Hz, 1H, ArH), 8.26 (t, J=1.73 Hz, 1H, ArH), 8.22 (d, J=8.61 Hz, 3H, ArH), 7.95 (m, 2H, ArH), 7.79 (m, 5H, ArH & ═C(NH2)2), 7.69 (d, J=2.52 Hz, 1H, ArH), 7.66 (d, J=8.61 Hz, 2H, ArH), 7.58 (d, J=2.43 Hz, 1H, ArH), 7.43 (t, J=7.98 Hz, 1H, ArH), 6.95 (d, J=6.71 Hz, 1H, ArH), 3.15 (s, 6H, ArN(CH3)2), 2.37 (s, 3H, Ar(CH3)═N—); LCMS (APCI+): 482 (100%); HPLC: 95.8%.
