Procedure

A mixture of 2-[4-(2,6-difluoro-benzoylamino)-1H-pyrazol-3-yl]-1H-benzimidazole-5-carboxylic acid (115 mg, 0.30 mmol), 1-methyl-piperazine (50.0 μL, 0.45 mmol), EDC (104 mg, 0.54 mmol) and HOBt (73.0 mg, 0.54 mmol) in DMF (5 ml) was stirred at ambient temperature for 14 h. The residue was reduced in vacuo, taken up in EtOAc and washed with water and brine, dried (MgSO4) and reduced in vacuo to give 2,6-difluoro-N-{3-[5-(4-methyl-piperazine-1-carbonyl)-1H-benzimidazol-2-yl]-1H-pyrazol-4-yl}-benzamide (37 mg, 26%) as a pale yellow solid. (LC/MS: Rt 1.78, [M+H]+ 466.09).
