実験手順

4-{6-[8-Cyclopentyl-6-(2-ethoxy-ethoxy)-7-oxo-7,8-dihydro-pyrido[2,3-d]pyrimidin-2-ylamino]-pyridin-3-y}-piperazine-1-carboxylic acid tert-butyl ester (70 mg, 0.12 mmol) was dissolved in CH2Cl2 (2.5 mL) and 2 M HCl in ether (2.5 mL) was added. This mixture was stirred for 2 h at room temperature and a yellow precipitate formed. The solvents were removed under reduced pressure and the resulting solid was suspended in ether and collected by filtration then dried overnight in vacuo at 50° C. to give 8-cyclopentyl-6-(2-ethoxy-ethoxy)-2-(5-piperazin-1-yl-pyridin-2-ylamino)-8H-pyrido[2,3-d]pyrimidin-7-one hydrochloride salt (30 mg, 52%).
