Procedure

3-Bromo-N-(4-(trifluoromethoxy)phenyl)benzamide (Stage 3.1, 50 mg, 0.139 mmol), 5-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)pyrazin-2-amine (0.180 mmol), 2 M Na2CO3 (0.104 mL, 0.208 mmol), (Ph3P)4Pd (8 mg, 6.94 μmol), water (0.8 mL) and DME (2.4 mL) were added to a vial, which was sealed and subjected to MW irradiation at 150° C. for 10 min. The RM was filtered through a PL-Thiol MP SPE cartridge (StratoSpheres™, 6 mL) and the cartridge was washed with MeOH (10 mL). The combined filtrates were evaporated to dryness under reduced pressure and the crude product was purified by preparative HPLC to afford the title compound. UPLC-MS (Condition 6) tR=1.84 min, m/z=375.3 [M+H]+.
