Procedure

To a solution of HATU (0.3 mmol, 113 mg) and 5-(2-chloro-5-(3-fluoropyridin-2-yl)benzamido)-1-phenyl-1H-pyrazole-3-carboxylic acid (Example 105, 0.23 mmol, 100 mg) in DMF (0.9 mL) was added DIPEA (1.10 mmol, 0.191 mL). The solution was stirred at room temperature for 15 minutes. 3-methyl-1H-pyrazol-4-amine (0.23 mmol, 100 mg) was added and the reaction stirred at room temperature for 18 hours. The reaction was diluted with EtOAc (20 mL), washed with NaHCO3 (20 mL), 10% aqueous citric acid solution (20 mL) and brine (20 mL). The organic layer was dried over sodium sulphate and concentrated in vacuo. The residue was purified using reverse phase column chromatography to afford the title compound as a yellow solid (35 mg, 29%).
