(S)-3-Bromo-4-(3-hydroxypyrrolidin-1-yl)-N-(4-(trifluoromethoxy)phenyl)benzamide (Stage 1.1, 80 mg, 0.180 mmol), pyrimidin-5-ylboronic acid (66.8 mg, 0.539 mmol), Pd(PPh3)2Cl2 (7.57 mg, 10.78 μmol) and Na2CO3 (57.1 mg, 0.539 mmol) were added to a MW vial and was treated with a mixture of DME (762 μL), water (218 μL) and EtOH (109 μL). The vial was sealed, evacuated/purged with argon and the RM was subjected to MW irradiation at 80° C. for 2 h. The RM was cooled to RT, diluted with THF (1 mL) and treated with Si-Thiol (Silicycle, 1.27 mmol/g, 70.7 mg, 0.090 mmol), filtered and the filtrate was evaporated off under reduced pressure to give a residue which), filtered and the filtrate was evaporated off under reduced pressure to give a residue which was purified by flash chromatography (RediSep® Silica gel column, 4 g, cyclohexane/EtOAc-EtOH+0.1% NH4OH (8:2), from 30% to 80% EtOAc-EtOH+0.1% NH4OH (8:2) to yield the title compound as a yellow solid.
