Reaction Steps

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 (0.055 g, 0.109 mmol) was dissolved in ethyl acetate (3 mL) and 1 N aqueous HCl (2 mL) and stirred at room temperature for 48 hours. The reaction mixture was diluted with dichloromethane and aqueous NaHCO3. The layers were separated and the organic layer was dried over MgSO4, filtered, and the solvent evaporated to give 6-acetyl-8-cyclopentyl-2-[5-(2,6-dimethyl-morpholin-4-yl)-pyridin-2-ylamino]-5-methyl-8H-pyrido[2,3-d]pyrimidin-7-one (0.020 g, 38.4%). MS (APCl) Calc'd for M+1: 477.3. Found: 477.2. 1H NMR δ(400 MHz, CDCl3) 8.79 (s, 1H), 8.1 (d, J=9.0 Hz, 1H), 8.00 (d, J=2.7 Hz, 1H), 7.90 (s, 1H), 7.30 (dd, J=3.1, 9.3 Hz, 1H), 5.87 (m, 1H), 3.83 (m, 2H), 3.37 (d, J=10.0 Hz, 2H), 2.54 (s, 3H), 2.46 (dd, J=11.7, 11.7, 2H), 2.37 (s, 3H), 2.32 (m, 2H), 2.05 (m, 2H), 1.87 (m, 2H), 1.68 (m, 2H), 1.27 (d, J=6.4 Hz, 6H).
