A mixture of 5-bromo-6-(2-hydroxyethoxy)-N-(4-(trifluoromethoxy)phenyl)nicotinamide (Stage 52.1, 50 mg, 0.119 mmol), Pd(Ph3P)4 (14 mg, 0.012 mmol) and 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrimidine (37 mg, 0.178 mmol) in toluene (0.5 mL) was stirred for 15 min. at RT. K3PO4 (76 mg, 0.356 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 12% to 17% in 6 min.) to afford the title compound as an off-white powder.
