Procedure
To a solution of 2-[3-[5-chloro-2-(difluoromethoxy)phenyl]-4-[pyrazolo[1,5-a]-pyrimidine-3-amido]-1H-pyrazol-1-yl]acetic acid (100 mg, 0.22 mmol) in DMF (10 mL) was added dimethyl[2-(piperazin-1-yl)ethyl]amine (68 mg, 0.43 mmol), DIEA (125 mg, 0.97 mmol) and HATU (123 mg, 0.32 mmol). The resulting solution was stirred at room temperature overnight and concentrated under vacuum. The crude product was purified by Prep-HPLC with the following conditions (2#-Analyse HPLC-SHIMADZU(HPLC-10)): Column, XBridge BEH130 Prep C18 OBD Column, 19� 100 mm 5 um 13 nm; mobile phase, Water with 10 mM NH4CO3 and ACN (15% ACN up to 40% in 6 min); Detector, UV 254/220 nm. This resulted in 79.1 mg (61%) of N-[3-[5-chloro-2-(difluoromethoxy)phenyl]-1-(2-[4-[2-(dimethylamino)ethyl]piperazin-1-yl]-2-oxoethyl)-1H-pyrazol-4-yl]pyrazolo[1,5-a]pyrimidine-3-carboxamide as a light yellow solid. LCMS (Method 25) [M+H]+=602.2, RT=0.89 min. 1H NMR (300 MHz, DMSO-d6) δ: (ppm) 9.75 (s, 1H), 9.34 (dd, 1H, J=1.7, 7.1 Hz), 8.69-8.67 (m, 2H), 8.30 (s, 1H), 7.62 (dd, 1H, J=2.7, 8.7 Hz), 7.55 (d, 1H, J=2.7 Hz), 7.45 (d, 1H, J=9.0 Hz), 7.28 (dd, 1H, J=4.2, 6.9 Hz), 7.02 (t, 1H, J=73.2 Hz), 5.23 (s, 2H), 3.48-3.42 (m, 4H), 2.45-2.32 (m, 8H), 2.13 (s, 6H).
