Procedure
To a solution of N-[3-[5-chloro-2-(difluoromethoxy)phenyl]-1-(oxiran-2-ylmethyl)-1H-pyrazol-4-yl]pyrazolo[1,5-a]pyrimidine-3-carboxamide (50 mg, 0.11 mmol) in N,N-dimethylformamide (1 mL), DIEA (67 mg, 0.518 mmol) and morpholine (14 mg, 0.161 mmol) was added at room temperature. The resulting solution was stirred at 60° C. overnight, cooled, diluted with 30 mL of ethyl acetate, washed with 2×10 mL of water and 2×10 mL of brine. The organic layer was dried over anhydrous sodium sulfate and concentrated under vacuum. The residue was purified by flash chromatography on silica gel eluting with dichloromethane/methanol (95/5). This resulted in 50 mg of crude product, which was purified by Flash-Prep-HPLC with the following conditions (IntelFlash-1): Column: X Bridge C18, 19*150 mm, 5 um; Mobile Phase A: Water/0.05% NH4HCO3, Mobile Phase B: ACN; Flow rate: 20 mL/min; Gradient: 30% B to 70% B in 10 min; 254 nm to obtain 40 mg (67%) of N-[3-[5-chloro-2-(difluoromethoxy)phenyl]-1-[2-hydroxy-3-(morpholin-4-yl)propyl]-1H-pyrazol-4-yl]pyrazolo[1,5-a]pyrimidine-3-carboxamide as a white solid. LCMS (Method 35) [M+H]+=548.2, RT=2.28 min. 1H-NMR (300 MHz, DMSO-d6): δ (ppm) 9.73 (s, 1H), 9.33 (dd, 1H, J=1.5, 7.2 Hz), 8.68-8.67 (m, 2H), 8.34 (s, 1H), 7.65 (d, 1H, J=2.7 Hz), 7.61 (s, 1H), 7.44 (d, 1H, J=8.7 Hz), 7.27 (dd, 1H, J=4.2, 6.9 Hz), 7.00 (t, 1H, J=73.5 Hz), 4.99 (d, 1H, J=4.5 Hz), 4.31-4.28 (m, 1H), 4.13-4.07 (m, 2H), 3.56 (t, 4H, J=4.5 Hz), 2.42 (t, 4H, J=4.5 Hz), 2.32 (d, 2H, J=4.8 Hz).
