Reaction Steps

4-Bromo-3-iodo-N-(4-(trifluoromethoxy)phenyl)benzamide (Stage 117.2, 3 g, 6.17 mmol), pyrimidin-5-ylboronic acid (841 mg, 6.79 mmol), Pd(PPh3)2Cl2 (217 mg, 0.309 mmol) and Na2CO3 (1.963 g, 18.52 mmol) in a mixture of DME (17.28 mL), water (4.94 mL), EtOH (2.469 mL) was degassed and stirred at 80° C. for 23 h under argon. Additional pyrimidin-5-ylboronic acid (76 mg, 0.613 mmol) was added to the RM and stirring was continued for 5 h. The RM was treated with Si-Thiol (Silicycle, 1.27 mmol/g, 1.215 g, 1.543 mmol), filtered and the filtrate was evaporated off under reduced pressure to give a residue which was purified by flash chromatography (Silica gel column, 80 g, cyclohexane/EtOAc, from 10% to 45% EtOAc) to yield the title compound as a white crystalline solid. UPLC-MS (condition 1) tR=2.80 min, m/z=437.9-439.9 [M+H]+, m/z=436.0-438.0 [M−H]−.
