Procedure

To a solution of (±)-1-methyl-5-(3-(trifluoromethyl)piperazin-1-yl)-1H-pyrazol-4-amine (300 mg, 2.05 mmol), 5-(tert-butoxycarbonylamino)-2-(2,6-difluorophenyl)thiazole-4-carboxylic acid from Example 25 (516 mg, 1.73 mmol), HATU (0.54 g, 1.73 mmol) in DMF (15 mL) was added TEA (1.1 mL). The reaction mixture was stirred at 25° C. for 20 hours, poured into water (100 mL), and extracted with EtOAc (50 mL×2). The combined organic layers was washed with water (50 mL×2) and brine (30 mL×2), dried over Na2SO4, filtered, and concentrated under reduced pressure to give a residue. The residue was purified by silica gel chromatography using DCM/MeOH (1:1) as eluting solvents to afford tert-butyl (±)-2-(2,6-difluorophenyl)-4-(1-methyl-5-(3-(trifluoromethyl)piperazin-1-yl)-1H-pyrazol-4-ylcarbamoyl)thiazol-5-ylcarbamate (380 mg, 52%) as white solid. MS (ESI) m/z: 588 (M+1+).
