Procedure

A mixture of 2-fluoro-6-methoxy-benzoic acid (20 mg, 0.12 mmol), 1-(4-methoxy-benzyl)-3-(5-morpholin-4-ylmethyl-1H-benzimidazol-2-yl)-1H-pyrazol-4-ylamine (50 mg, 0.12 mmol), EDC (116 mg, 0.14 mmol) and HOBt (81 mg, 0.14 mmol) was stirred at room temperature in DMF (2 ml) for 20 h. The mixture was reduced in vacuo and the residue partitioned between EtOAc (5 ml) and water (2 ml) and the organic portion washed with saturated aqueous sodium hydrogen carbonate, dried (MgSO4) and reduced in vacuo. The residue was purified by flash column chromatography [SiO2, EtOAc] to give 2-fluoro-6-methoxy-N-[1-(4-methoxy-benzyl)-3-(5-morpholin-4-ylmethyl-1H-benzimidazol-2-yl)-1H-pyrazol-4-yl]-benzamide as a white solid (80 mg, 61%).
