実験手順

8-Cyclopentyl-6-(1-ethoxy-vinyl)-5-methyl-2-(5-morpholin-4-yl-pyridin-2-ylamino)-8H-pyrido[2,3-d]pyrimidin-7-one (0.490 g, 1.03 mmol) was dissolved in dichloromethane (5 mL). 2 N HCl in diethyl ether (3 mL) was added and the resulting mixture was stirred at room temperature for 4 hours. Then, additional 2 N HCl in diethyl ether (2 mL) was added and the mixture was stirred for an additional 12 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 a yellow solid. The solid was recrystallized from a mixture of hexanes, ethyl acetate and dichloromethane to give 6-acetyl-8-cyclopentyl-5-methyl-2-(5-morpholin-4-yl-pyridin-2-ylamino)-8H-pyrido[2,3-d]pyrimidin-7-one as a yellow solid (0.280 g, 60.7%).
