Procedure

6-Bromo-8-cyclopentyl-2-[5-(2,6-dimethyl-morpholin-4-yl)-pyridin-2-ylamino]-5-methyl-8H-pyrido[2,3-d]pyrimidin-7-one (0.062 g, 0.121 mmol), tetrakis(triphenylphosphine)palladium (0.017 g, 0.015 mmol) and tributyl-(1-ethoxy-vinyl)-stannane (0.068 mg, 0.188 mmol) were dissolved in toluene (2 mL) and slowly brought to reflux for 12 hours. Additional tetrakis(triphenylphosphine)palladium (0.010 g) was added and the reaction brought to reflux for 16 hours. The reaction mixture was cooled and purified by silica gel chromatography to 8-cyclopentyl-2-[5-(2,6-dimethyl-morpholin-4-yl)-pyridin-2-ylamino]-6-(1-ethoxy-vinyl)-5-methyl-8H-pyrido[2,3-d]pyrimidin-7-one as a yellow solid (0.055 g, 90.2%). 1H NMR δ (400 MHz, CDCl3) 8.72 (s, 1H), 8.17 (d, J=9.0 Hz, 1H), 7.99 (d, J=2.9 Hz, 1H), 7.83 (s, 1H), 7.29 (dd, J=2.9, 9.0 Hz, 1H), 5.89 (m, 1H), 4.51 (d, J=2.5 Hz, 1H), 4.17 (d, J=2.4 Hz, 1H), 3.93 (q, J=7.1 Hz, 2H), 3.83 (m, 2H), 3.37 (d, J=10.3 Hz, 2H), 2.44 (dd, J=10.5, 10.5, 2H), 2.41 (s, 3H), 2.34 (m, 2H), 2.06 (m, 2H), 1.84 (m, 2H), 1.65 (m, 2H), 1.36 (t, J=7.1 Hz, 3H), 1.26 (d, J=6.4 Hz, 6H).
