Reaction Steps

To a mixture of 2-amino-3-nitro-benzoic acid sodium salt (205 mg, 1.0 mmol), 4-[2-(4-methyl-piperazin-1-yl)-ethyl]-phenylamine (219 mg, 1.0 mmol) and HATU (400 mg, 1.05 mmol) in DMF (2 mL) was added DIEA (0.52 mL, 388 mg, 3.0 mmol). The reaction mixture was stirred at room temperature for 1 h and heated at 70° C. for 1 h, and then evaporated under reduced pressure. The residue was purified by chromatography (50:10:1 CH2Cl2/MeOH/28% aqueous NH4OH) to afford the title compound (300 mg, 78%). 1H NMR (MeOH-d4) δ 2.44 (s, 3H), 2.50-2.85 (12H), 6.74 (dd, J=9 Hz and 9 Hz, 1H), 7.23 (d, J=9 Hz, 2H), 7.58 (d, J=9 Hz, 2H), 7.91 (d, J=9 Hz, 1H), 8.29 (d, J=9 Hz, 1H). ESI-MS m/z 384.5 (MH+).
