6-((3R,4R)-3-Hydroxy-4-(hydroxymethyl)pyrrolidin-1-yl)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-N-(4-(trifluoromethoxy)phenyl)nicotinamide (Stage 17.1, 50 mg, 0.096 mmol), 5-bromothiazole (78 mg, 0.478 mmol), Pd(Ph3P)4 (11.04 mg, 9.55 μmol), K3PO4 (81 mg, 0.382 mmol) toluene (478 μL) were added to a MW vial, which was sealed, evacuated/purged with argon and the RM was stirred for 16 h at 110° C. The RM was diluted with DME (2 mL)/EtOAc (1 mL), treated with Si-Thiol (Silicycle, 1.44 mmol/g, 39.8 mg, 0.057 mmol), centrifuged, the supernatant was filtered and the solvent was evaporated off under reduced pressure to give a residue which was purified by preparative SFC (Column Diol, isocratic at 30% in 8 min) to afford the title compound as an amber wax. UPLC-MS (Condition 3) tR=0.90 min, m/z=481.3 [M+H]+; 1H-NMR (400 MHz, DMSO-d6) δ ppm 2.05-2.15 (m, 1H) 2.99 (dd, J=10.79, 3.14 Hz, 1H) 3.18-3.23 (m, 1H) 3.22-3.28 (m, 1H) 3.39 (m, J=5.40 Hz, 2H) 3.52 (dd, J=11.30 Hz, 1H) 3.94-4.03 (m, 1H) 4.66 (t, J=5.27 Hz, 1H) 5.00 (d, J=4.27 Hz, 1H) 7.36 (d, J=8.41 Hz, 2H) 7.83-7.89 (m, 2H) 7.94 (d, J=0.50 Hz, 1H) 8.09 (d, J=2.38 Hz, 1H) 8.78 (d, J=2.38 Hz, 1H) 9.20 (d, J=0.50 Hz, 1H) 10.22 (s, 1H).
