Reaction Steps

A mixture of 4-(2,6-dichloro-benzoylamino)-1H-pyrazole-3-carboxylic acid (75 mg, 0.25 mmol), 4-morpholin-4-ylmethyl-benzene-1,2-diamine (52 mg, 0.25 mmol), EDC (58 mg, 0.3 mmol) and HOBt (41 mg, 0.3 mmol) in DMF (4 ml) was stirred at ambient temperature for 48 hours. The mixture was partitioned between EtOAc and saturated aqueous NaHCO3 and the organic portion washed with saturated aqueous NH4Cl, dried (MgSO4) and reduced in vacuo. The residue was taken up in AcOH and heated at 100° C. for 14 hours. cooled to ambient temperature and reduced in vacuo. The residue was purified via flash column chromatography eluting with CH2Cl2-MeOH (20:1-10:1) to give 2,6-dichloro-N-[3-(5-morpholin-4-ylmethyl-1H-benzimidazol-2-yl)-1H-pyrazol-4-yl]-benzamide (30 mg) as a pink solid. (LC/MS: Rt 2.12, [M+H]+ 471.14).
