5-Bromo-6-((2-hydroxyethyl)(methyl)amino)-N-(4-(trifluoromethoxy)phenyl)nicotinamide (Stage 151.1, 59 mg, 0.136 mmol), pyrimidin-5-ylboronic acid (33.7 mg, 0.272 mmol), Pd(PPh3)2Cl2 (9.54 mg, 0.014 mmol) and Na2CO3 (57.6 mg, 0.544 mmol) were added to a MW vial and treated with a mixture of DME (576 μL), water (165 μL) and EtOH (82 μL). The vial was sealed, evacuated/purged with argon and subjected to MW irradiation at 125° C. for 20 min, diluted with DME (3 mL) and treated with Si-Thiol (Silicycle, 1.44 mmol/g, 56.6 mg, 0.082 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 DEAP, from 10% to 15% in 10 min) to yield the title product as a white solid.
