Reaction Steps
3,3-Difluoropyrrolidine hydrochloride (69.8 mg, 0.486 mmol) and DIPEA (0.170 mL, 0.972 mmol) were added to 6-chloro-N-(4-(chlorodifluoromethoxy)phenyl)-5-(1H-pyrazol-5-yl)nicotinamide (Stage 48.1, 100 mg, 0.243 mmol) in iPrOH (0.5 mL) and stirred at 140° C. for 3 h. The RM was treated with water, and extracted with EtOAc. The combined extracts were dried over Na2SO4 and the solvent was evaporated off under reduced pressure to give the crude material which was purified by crystallization from DCM/EtOAc to give the title product as a white solid. HPLC (Condition 7) tR=6.746 min, UPLC-MS (Condition 3) tR=1.11 min, m/z=470.1 [M+H]+; 1H-NMR (400 MHz, DMSO-d6) δ ppm 2.32-2.45 (m, 2H) 3.42-3.51 (m, 2H) 3.56 (t, J=13.29 Hz, 2H) 6.48 (s, 1H) 7.34 (d, J=8.60 Hz, 2H) 7.73-7.88 (m, 3H) 8.13 (d, J=2.35 Hz, 1H) 8.79 (s, 1H) 10.30 (s, 1H) 13.01 (br.s, 1H).
