Reaction Steps

A mixture of N-(4-(chlorodifluoromethoxy)phenyl)-4-fluoro-3-(4-fluoro-1H-pyrazol-5-yl)benzamide (Stage 24.1, 62 mg, 0.147 mmol), R-3-hydroxypyrrolidine (0.031 mL, 0.206 mmol) and TEA (0.062 mL, 0.442 mmol) in DMSO (0.5 mL) was stirred at 100° C. for 16 h. The RM was diluted with EtOAc (30 mL), treated with sat. aq. Na2CO3 (20 mL) and extracted with EtOAc. The combined extracts were washed with water (20 mL) and brine (20 mL), dried over Na2SO4 and the solvent was evaporated off under reduced pressure to give a crude product which was purified by preparative HPLC (Condition 10). Fractions containing pure product were combined, treated with sat. aq. Na2CO3 and the MeCN was removed under reduced pressure. The aq. residue was extracted with DCM and the combined extracts were dried over Na2SO4 and the solvent was evaporated off under reduced pressure. The residue was dissolved in DCM and treated with n-hexane to give the title product as a white solid. HPLC (Condition 5) tR=6.61 min, UPLC-MS (Condition 3) tR=1.01 min, m/z=467.3 [M+H]+; 1H-NMR (400 MHz, DMSO-d6) δ ppm 1.69-1.95 (m, 2H) 2.79 (d, J=10.56 Hz, 1H) 3.06-3.20 (m, 2H) 3.22-3.35 (m, 1H) 4.13-4.30 (m, 1H) 4.79-4.96 (m, 1H) 6.75-6.92 (m, 1H) 7.31 (d, J=8.60 Hz, 2H) 7.86 (m, J=9.38 Hz, 5H) 10.11 (s, 1H) 12.67-13.12 (m, 1H).
