実験手順

To a solution of 5-(2,4-dichloro-5-(pyridin-2-yl)benzamido)-1-phenyl-1H-pyrazole-3-carboxylic acid (Example 111, 210 mg, 0.46 mmol), 3-methyl-1H-pyrazol-4-amine (68 mg, 0.69 mmol) and DIPEA (0.32 mL, 1.85 mmol) in anhydrous DMF (4 mL) was added 1-[bis(dimethylamino)methylene]-1H-1,2,3-triazolo[4,5-b]pyridinium 3-oxid hexafluorophosphate (264 mg, 0.69 mmol). The reaction was stirred at room temperature for 1 hour under nitrogen. The reaction was partitioned between EtOAc (20 mL) and water (20 mL). The organic layer was collected, washed with brine (15 mL), dried over sodium sulfate, filtered and concentrated in vacuo. The residue was purified by elution through an SCX-2 column using MeOH followed by 7N ammonia in MeOH, followed by purification using silica gel column chromatography eluting with EtOAc followed by 10% MeOH in DCM to afford the title compound (170 mg, 69%).
