Reaction Steps

Combine 7-methyl-2-(methylamino)pyrido[2,3-d]pyrimidin-6-yl trifluoromethanesulfonate (1.15 g, 3.57 mmol), 2-fluoro-4-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)aniline (0.896 g, 3.57 mmol), and NaHCO3 (0.899 g, 10.71 mmol) in dioxane (24 mL) and H2O (6 mL), sparge with argon, treat with Pd(PPh3)4 (0.206 g, 0.178 mmol) and heat to 60° C. overnight. Add additional 7-methyl-2-(methylamino)pyrido[2,3-d]pyrimidin-6-yl trifluoromethanesulfonate (120 mg, 0.37 mmol) and Pd(PPh3)4 (80 mg, 0.07 mmol), sparge the mixture with argon, and heat at 60° C. overnight. Cool the mixture to RT, treat with brine and extract with EtOAc (3×). Wash the combined organics with brine, dry over Na2SO4, concentrate to dryness and purify via silica gel chromatography (50-100% EtOAc/Hexanes) to afford the title compound (940 mg, 89% yield). MS (m/z): 298.1 (M+1).
