Procedure

To a solution of {3-(5-Chloro-2-difluoromethoxyphenyl)-4-[(pyrazolo[1,5-a]pyrimidine-3-carbonyl)amino]pyrazol-1-yl}acetic acid trifluoroacetate (100 mg, 0.17 mmol) in DMF (3 mL) was added methyl 3-[methyl(piperidin-4-yl)amino]propanoate hydrochloride (62 mg, 0.26 mmol), DIEA (67.2 mg, 0.52 mmol), HATU (79.2 mg, 0.21 mmol). The resulting solution was stirred at room temperature overnight and concentrated under vacuum. The residue was passed through a short pad of silica gel eluting with ethyl acetate/petroleum ether (10:1). The crude product was purified by Prep-HPLC with the following conditions (Prep-HPLC-005): Column, XBridge Prep C18 OBD Column, 5 um, 19*150 mm; mobile phase, water with 0.05% FA and MeCN (37.0% up to 43.0% in 10 min, up to 95.0% in 1 min, hold 95.0% in 1 min, down to 37.0% in 2 min); Detector, UV 254/220 nm. This resulted in 45.2 mg (38%) of the formic acid salt of methyl 3-[[1-(2-[3-[5-chloro-2-(difluoromethoxy)phenyl]-4-[pyrazolo[1,5-a]pyrimidine-3-amido]-1H-pyrazol-1-yl]acetyl)piperidin-4-yl](methyl)amino]propanoate as an off-white solid.
