Procedure
5-Bromo-6-chloro-N-(4-(trifluoromethoxy)phenyl)nicotinamide (Stage 35.1, 2 g, 4.48 mmol), pyrimidin-5-ylboronic acid (0.666 g, 5.38 mmol), Pd(PPh3)2Cl2 (0.315 g, 0.448 mmol) and Na2CO3 (1.425 g, 13.45 mmol) were added to a MW vial. The vial was sealed, evacuated/purged with argon, and DME (12.55 mL), water (3.59 mL), EtOH (1.793 mL) were added. The RM was stirred at 80° C. for 3.5 h, diluted with THF (4 mL), treated with Si-Thiol (Silicycle, 1.27 mmol/g, 1.765 g, 2.241 mmol), filtered and the filtrate was evaporated off under reduced pressure to give a residue which was purified by flash chromatography (RediSep® Silica gel column, 120 g, cyclohexane/EtOAc-EtOH+0.1% NH4OH (9:1), from 60% to 90% EtOAc-EtOH+0.1% NH4OH (9:1)). Crystallization from a toluene/EtOH mixture yielded the title compound as a white amorphous solid.
