Procedure

3-Bromo-N-(4-(trifluoromethoxy)phenyl)benzamide (Stage 3.1, 50 mg, 0.139 mmol), 1-((5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)thiophen-2-yl)methyl)pyrrolidine (0.180 mmol), (Ph3P)4Pd (8 mg, 6.94 μmol) 2 M Na2CO3 (0.104 mL, 0.208 mmol), 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 600 sec (very high absorbance). The RM was filtered through a PL-Thiol MP SPE cartridge (StratoSpheres™, 6 mL), the cartridge was washed with MeOH (10 mL) and the combined filtrates were evaporated under reduced pressure to give the crude product was purified by preparative HPLC to afford the title compound. UPLC-MS (Condition 6) tR=1.92 min, m/z=447.4 [M+H]+.
