Versuchsvorschrift

6-Bromo-8-cyclopentyl-5-methyl-2-(5-morpholin-4-yl-pyridin-2-ylamino)-8H-pyrido[2,3-d]pyrimidin-7-one (0.290 g, 0.597 mmol), tetrakis(triphenylphosphine)palladium (0.083 g, 0.072 mmol) and tributyl-(1-ethoxy-vinyl)-stannane (0.336 g, 0.932 mmol) were dissolved in toluene (4 mL) and slowly brought to reflux for 3 hours. The reaction mixture was purified by silica gel chromatography to give 8-cyclopentyl-6-(1-ethoxy-vinyl)-5-methyl-2-(5-morpholin-4-yl-pyridin-2-ylamino)-8H-pyrido[2,3-d]pyrimidin-7-one as a yellow solid (0.110 g, 38.6%). 1H NMR δ (400 MHz, DMSO-d6) 8.95 (s, 1H), 8.83 (s, 1H), 8.02 (d, J=2.9 Hz, 1H), 7.86 (d, J=9.0 Hz, 1H), 7.44 (dd, J=3.2, 9.3 Hz, 1H), 5.79 (m, 1H), 4.42 (d, J=2.0 Hz, 1H), 4.01 (d, J=2.0 Hz, 1H), 3.79 (q, J=6.8 Hz, 2H), 3.72 (m, 4H), 3.09 (m, 4H), 2.34 (s, 3H), 2.17 (m, 2H), 1.85 (m, 2H), 1.71 (m, 2H), 1.55 (m, 2H), 1.21 (m, 3H).
