実験手順

A mixture of 6-chloro-N-(4-(chlorodifluoromethoxy)phenyl)-5-(1H-pyrazol-5-yl)nicotinamide (Stage 48.1, 63 mg, 0.156 mmol), (3S,4S)-4-(dimethylamino) pyrrolidin-3-ol (50.8 mg, 0.250 mmol) and DIPEA (0.191 mL, 1.094 mmol) and iPrOH (1 mL) in a sealed vial was heated at 110° C. for 4 h The RM was treated with sat. aq. Na2CO3 (20 mL) and extracted with EtOAc. The combined extracts were washed with brine (10 mL), dried over Na2SO4 and the solvent was evaporated off under reduced pressure to give a crude product which was purified by preparative SFC (Column 4-EP, isocratic 25% in 15 min) followed by preparative HPLC (Condition 10). Fractions containing product were combined, treated with sat. aq. Na2CO3 and the MeCN was evaporated off under reduced pressure to give an aq. residue which was extracted with DCM. The combined extracts were dried over Na2SO4 and the solvent was evaporated off under reduced pressure to give the title product as a white foam. HPLC (Condition 7) tR=5.71 min, UPLC-MS (Condition 3) tR=0.78 min, m/z=493 [M+H]+; 1H-NMR (400 MHz, DMSO-d6) δ ppm 2.14 (s, 6H) 2.95-3.03 (m, 1H) 3.16-3.26 (m, 2H) 3.34-3.46 (m, 2H) 4.00-4.13 (m, 1H) 4.97-5.13 (m, 1H) 6.33-6.45 (m, 1H) 7.34 (d, J=8.99 Hz, 2H) 7.80-7.91 (m, J=9.40 Hz, 3H) 8.04 (s, 1H) 8.68-8.81 (m, 1H) 10.20 (s, 1H) 12.88-13.16 (m, 1H).
