5-Bromo-6-morpholino-N-(4-(trifluoromethoxy)phenyl)nicotinamide (Stage 148.1, 60 mg, 0.134 mmol), (6-(hydroxymethyl)pyridin-3-yl)boronic acid (41.1 mg, 0.269 mmol), Pd(PPh3)2Cl2 (9.44 mg, 0.013 mmol) and Na2CO3 (42.8 mg, 0.403 mmol) were added to a MW vial and treated with a mixture of DME (570 μL), water (163 μL) and EtOH (81 μL). The vial was sealed, evacuated/purged with argon and subjected to MW irradiation at 125° C. for 20 min and then at 130° C. for 20 min, diluted with DME (2 mL) and treated with Si-Thiol (Silicycle, 1.44 mmol/g, 46.7 mg, 0.067 mmol). The RM was 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 2-EP, from 15% to 20% in 6 min) to yield the title product as a white solid.
