实验步骤: To a solution of the crude of 2-[2-hydroxy-5-(2-methoxy-pyridin-3-yl)-phenyl]-7-methyl-3H-benzoimidazole-5-carboxylic acid (estimated 0.4 mmol), 4-[2-(4-methyl-piperazin-1-yl)-ethyl]-phenylamine (88 mg, 0.4 mmol) and HATU (167 mg, 0.44 mmol) in DMF (5 mL) was added DIEA (0.5 mL, 371 mg, 2.87 mmol). The reaction mixture was stirred at room temperature for 2 h and heated at 60° C. for 15 h, and then evaporated to dry under reduced pressure. The residue was diluted with DMSO (1.5 mL), filtered and then purified with using HPLC (TFA/H2O/CH3CN) to afford the title compound (34.5 mg, 11% from two steps from 3,4-diamino-5-methyl-benzoic acid). 1H NMR (MeOH-d4) δ 2.77 (s, 3H), 2.90 (s, 3H), 2.97-3.43 (12H), 3.97 (s, 3H), 7.09 (m, 1H), 7.22 (d, J=9 Hz, 1H), 7.31 (d, J=9 Hz, 2H), 7.70 (d, J=9 Hz, 2H), 7.82-7.84 (2H), 7.91 (s, 1H), 8.17 (m, 1H), 8.20 (s, 1H), 8.31 (s, 1H). ESI-MS m/z 577.5 (MH+). heated at 60° C. for 15 h evaporated to dry under reduced pressure The residue was diluted with DMSO (1.5 mL) filtered purified with using HPLC (TFA/H2O/CH3CN)

实验步骤: 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+). heated at 70° C. for 1 h evaporated under reduced pressure The residue was purified by chromatography (50:10:1 CH2Cl2/MeOH/28% aqueous NH4OH)
