Reaction Steps

4-[tert-Butyl(dimethyl)silyl]oxyaniline (1.8 g, 8 mmol) and 5-bromo-2-ethoxy-pyrimidine (1.6 g, 8 mmol) dissolved in anhydrous tetrahydrofuran (30 mL) are stirred for 1 hour at ambient temperature in the presence of sodium tert-butylate (4 mL, 2M solution in THF) and chloro(2-di-tert-butylphosphino-2′,4′,6′-triisopropyl-1,1′-biphenyl)[2-(2-aminoethyl)-phenyl]palladium(II) (111 mg, 0.16 mmol). The reaction mixture is filtered over Celite and then evaporated to dryness. The residue is triturated in heptane to obtain the expected compound after filtration.
