Reaction Steps

To a solution of compound B3 (150 mg, 0.37 mmol) in EtOH (15 mL) and H2O (7.5 mL) was added 4-chloroquinoline (73 mg, 0.45 mmol) and stirred until it dissolved, then 2 drops of c.HCl was added. The reaction mixture was refluxed for 20 h, diluted with EtOAc, brought to boil and cool to 20° C. The resulting precipitate was filtered and recrystallized from MeOH/EtOAc/Charcoal/Celite to give Cpd. FF1 (195 mg, 96%) as a yellow solid.; M.P (MeOH/EtOAc)>300° C.; 1H NMR [(CD3)2SO] δ13.72 (v br, 2H , 2×N+H), 10.91 (br s, 1 H, NH), 10.96 (br s, 1 H, NH), 10.56 (s, 1 H, HN), 8.79 (d, J=8.5 Hz, 1 H, ArH), 7.50 (d, J=6.9 Hz, 1 H, ArH), 8.14-7.99 (m, 6 H, ArH & NH2), 7.83 (m, 3 H, ArH), 7.55 (t, J=7.9 Hz, 1 H, ArH), 7.49 (d, J=8.8 Hz, 2 H, ArH), 6.78 (d, J=6.9 Hz, 1 H, ArH), 6.24 (s, 1 H, ArH), 2.30 (s, 3 H, ArH), mass APCI+ 476.
