Versuchsvorschrift

To a mixture of 4-[1-(4-amino-5-oxopyrido[2,3-d]pyrimidin-8(5H)-yl)ethyl]-2-bromo-6-chloro-3-ethoxybenzonitrile (20 mg, 0.04 mmol) and {6-[(dimethylamino)carbonyl]pyridin-3-yl}boronic acid (13 mg, 0.069 mmol) in acetonitrile (2 mL, 40 mmol) was added sodium carbonate (10 mg, 0.09 mmol) in water (0.5 mL, 30 mmol). The reaction was degassed with bubbling nitrogen. [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) complex with dichloromethane (1:1) (2 mg, 0.002 mmol) was added and degassed more with N2. Reaction was heated at 100° C. for 1 h. The crude product was purified on preparative LC-MS (acetonitrile, water, TFA) to give the desired product (0.005 g, 20%) as white amorphous solid. The product was isolated as a racemic mixture. LCMS calculated for C26H24ClN7O3(M+H)+: m/z=518.1; found: 518.1.
