A mixture of 5-bromo-6-(2-methoxyethoxy)-N-(4-(trifluoromethoxy)phenyl)nicotinamide (Stage 51.1, 50 mg, 0.115 mmol) Pd(Ph3P)4 (13 mg, 0.011 mmol) and 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrimidine (36 mg, 0.172 mmol) and toluene (0.5 mL) was stirred for 15 min. at RT. K3PO4 (73 mg, 0.345 mmol) was added and the RM was stirred at 110° C. for 6 h. The RM was diluted with MeOH, filtered through a cartridge of PL-Thiol MP-Resin, and the filtrate was evaporated to dryness under reduced pressure. The residue was purified by preparative SFC (Column DEAP, from 7% to 12% in 6 min) to afford the title compound was lyophilized to afford an off-white powder. UPLC-MS (Condition 2) tR=1.04 min, m/z=435.1 [M+H]+.
