Reaction Steps

A mixture of the ethyl ester (103 mg, 0.60 mmol), 4-(2,6-difluoro-benzoylamino)-1H-pyrazole-3-carboxylic acid (134 mg, 0.50 mmol), EDC (115 mg, 0.60 mmol) and HOBt (81 mg, 0.60 mmol) in DMF (5 ml) was stirred at ambient temperature for 16 hours. The mixture was reduced in vacuo, the residue taken up in EtOAc and washed successively with saturated aqueous sodium bicarbonate, water and brine. The organic portion was dried (MgSO4) and reduced in vacuo to give 4-{[4-(2,6-difluoro-benzoylamino)-1H-pyrazole-3-carbonyl]-amino}-cyclohexanecarboxylic acid ethyl ester (112 mg).
