To a solution of 5-(2,4-dichloro-5-(pyridin-2-yl)benzamido)-1-phenyl-1H-pyrazole-3-carboxylic acid (Example 111, 110 mg, 0.24 mmol), 3,5-dimethyl-1H-pyrazol-4-amine (30 mg, 0.27 mmol) and DIPEA (0.17 mL, 0.97 mmol) in DMF (1.5 mL) was added 1-[bis(dimethylamino)methylene]-1H-1,2,3-triazolo[4,5-b]pyridinium 3-oxid hexafluorophosphate (101 mg, 0.26 mmol) and the reaction was stirred for 2 hours at room temperature. The reaction was concentrated in vacuo and the residue purified using Preparative HPLC to afford the title compound (65 mg, 49%).
