Reaction Steps

In a 40 mL vial, chloro(2-dicyclohexylphosphino-2′,4′,6′-triisopropyl-1,1′-biphenyl)[2-(2-aminoethyl)phenyl)]palladium(II) (0.025 g, 0.031 mmol), tert-butyl 3-((6-methoxy-2-(methylthio)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrimidin-4-yl)amino)piperidine-1-carboxylate (0.15 g, 0.312 mmol), 2-bromo-5-fluoropyrimidine (0.083 g, 0.468 mmol) and CuCl (0.031 g, 0.312 mmol) were combined, then purged with argon. Then degassed DMF (3 mL) followed by Cs2CO3 (0.407 g, 1.249 mmol) were added to the vial. The reaction was then heated at 100° C. for 18 h. The mixture was cooled, diluted with ethyl acetate, washed with water, dried (Na2SO4), filtered and the solvent was evaporated under reduced pressure. The material was purified by column chromatography on silica gel (0-100% EtOAc in hexanes) to afford the desired product. MS (m/z)=451 (M+H).
