To a solution of 3-bromo-N-[(4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl]-5-[ethyl(oxan-4-yl)amino]-2-fluoro-6-methylbenzamide (112 mg, 0.23 mmol) in 1,4-Dioxane (2 ml) and Water (1 ml) was added 4-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzyl]morpholine (103 mg, 0.34 mmol) followed by Na2CO3 (84.04 mg, 0.79 mmol). The solution was purged with nitrogen for 5 minutes before the addition of palladium-triphenylphosphine (1:4) (26 mg, 0.02 mmol). The yellow mixture was then purged with nitrogen for 5 minutes before being heated to 100° C. After 4 hours LCMS indicated no unreacted starting material was present. The darken reaction mixture was diluted with deionized water (5 ml) and extracted with 10% MeOH in DCM (5×5 ml). The combined organic extracts were dried over MgSO4, filtered and concentrated under reduced pressure. The residue was purified by FCC (5 g silica, Isolute cartridge, gradient of eluents; 99:1 DCM:MeOH to 95:5 DCM:MeOH) to give 69 mg (52%) of the title compound as an off-white solid.
