Procedure

(R)-5-Bromo-6-(3-hydroxypyrrolidin-1-yl)-N-(4-((trifluoromethyl)thio)phenyl)nicotinamide (Stage 186.1, 92 mg, 0.2 mmol) and pyrimidin-5-ylboronic acid (49.6 mg, 0.4 mmol) were dissolved in DME (0.8 mL). A solution of 2 M Na2CO3 (0.300 mL, 0.6 mmol) was added, the mixture was flushed with argon, heated to 100° C. in a pressure safe vial, then Pd(PPh3)2Cl2 (14 mg, 0.02 mmol) was added. The RM was stirred under argon at 80-90° C. for 2 h. After cooling at RT, the RM was dissolved in EtOAc and washed with brine. The organic phase was dried over Na2SO4 and the solvent was evaporated off under reduced pressure to give a residue that was purified by flash chromatography (RediSep® Silica gel column, (DCM/MeOH 98:2)/MeOH, from 0 to 5% MeOH) and treated with Si-Thiol (80 mg) in MeOH to afford the title compound as a beige crystalline powder.
