Reaction Steps

1,2-Epoxy-3,3,3-trifluoropropane(84 mg; 0.72 mmol; 2.4 eq.) was added to a solution of 2-[3-(1-methyl-1H-pyrazol-4-yl)phenyl]-5-(1-piperidin-4-yl-1H-pyrazol-4-yl)pyrimidine (example 1, 200 mg; 0.31 mmol; 1.0 eq.) and DIEA (53 μl; 0.31 mmol; 1.0 eq.) in DMF (4 mL). The reaction mixture was stirred at 50° C. O/N. It was then diluted with water and extracted with EtOAc (three times). Combined organic phases were washed with water and brine, dried over magnesium sulfate, filtered and concentrated. Purification by flash chromatography on silica (DCM:EtOAc, gradient from 40:60 to 0:100) afforded the title compound as a beige powder (56 mg, 36%). 1H NMR (300 MHz, DMSO-d6) δ 9.17 (s, 2H), 8.59-8.49 (m, 2H), 8.27 (s, 1H), 8.25-8.18 (m, 1H), 8.14 (s, 1H), 7.93 (s, 1H), 7.75-7.67 (m, 1H), 7.52 (t, J=7.7 Hz, 1H), 6.24-6.13 (m, 1H), 4.28-4.08 (m, 2H), 3.90 (s, 3H), 3.12-2.97 (m, 2H), 2.66-2.53 (m, 2H), 2.36-2.17 (m, 2H), 2.12-1.86 (m, 4H). HPLC (Condition A): Rt 2.85 min (purity 98.4%). MS (ESI+): 498.4.
