Procedure

To solution of 5-(2,4-dichloro-5-(pyridin-2-yl)benzamido)-1-phenyl-1H-pyrazole-3-carboxylic acid (Example 111, 200 mg, 0.44 mmol) in DMF was added DIPEA (0.46 mL, 2.65 mmol) and 2-(3H-[1,2,3]triazolo[4,5-b]pyridin-3-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (201 mg, 0.53 mmol). The reaction was stirred at room temperature for 10 minutes before the addition of (1H-pyrazol-4-yl)methanamine hydrochloride (64 mg, 0.49 mmol). The reaction was stirred at room temperature for 18 hours. The reaction mixture was diluted with ethyl acetate (50 mL) and extracted with water (3×5 mL) and brine (25 mL). The organic layer was collected, dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was purified using silica gel column chromatography eluting with 2% MeOH in DCM to afford the title compound (68 mg, 29%).
