Reaction Steps

5-Bromo-6-chloro-N-(4-(trifluoromethoxy)phenyl)nicotinamide (Stage 12.2, 1 g, 2.53 mmol) and (Rac.)-pyrrolidin-3-ol (264 mg, 3.03 mmol) and DIPEA (883 μL, 5.06 mmol), in iPrOH (4213 μL) were added a MW vial and heated at 140° C. for 30 min. The RM was evaporated to dryness under reduced pressure, treated with 0.5 M HCl (10 mL) and EtOAc (20 mL) and extracted with EtOAc. The combined extracts were washed with water, dried over MgSO4 and evaporated to dryness under reduced pressure. Trituration of the residue in cyclohexane and filtration of the solid afforded the title compound as an off-white solid. UPLC-MS (condition 1) tR=2.63 min, m/z=445.9-447.9 [M+H]+, m/z=444.0-446.0 [M−H]−; 1H-NMR (400 MHz, DMSO-d6) δ ppm 1.80-2.02 (m, 2H) 3.58 (d, J=11.49 Hz, 1H) 3.67-3.79 (m, 1H) 3.82-3.93 (m, 2H) 4.32-4.40 (m, 1H) 4.98 (br. s, 1H) 7.36 (d, J=8.56 Hz, 2H) 7.86 (d, J=9.05 Hz, 2H) 8.35 (d, J=1.96 Hz, 1H) 8.69 (d, J=1.96 Hz, 1H) 10.23 (s, 1H).
