To a solution of 2-[2-hydroxy-5-(2-methoxy-pyridin-3-yl)-phenyl]-3H-benzoimidazole-5-carboxylic acid (containing 1 equivalent of DMA, 44 mg, 0.1 mmol), 2-methoxy-4-(4-methyl-piperazin-1-yl)-phenylamine di HCl salt (29.4 mg, 0.1 mmol) and HATU (38 mg, 0.1 mmol) in DMF (1.2 mL) was added DIEA (45 mg, 0.35 mmol). The reaction mixture was stirred at room temperature for 2 h and heated at 60° C. for 3 h, and then evaporated 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 (26.4 mg, 39%). ESI-MS m/z 565.5 (MH+).
