4-[6-(6-Bromo-8-cyclopentyl-7-oxo-7,8-dihydro-pyrido[2,3-d]pyrimidin-2-ylamino)-pyridin-3-yl]-piperazine-1-carboxylic acid tert-butyl ester (0.26 g, 0.46 mmol) prepared as in Example 2 was dissolved in 1:1 chloroform/methanol (15 ml), to which was added diethyl ether (25 ml). The solution was purged with anhydrous hydrogen chloride gas and stoppered for 18 hours. The resulting white solid was filtered, washed with diethyl ether and dried in vacuo at 60° C. to give 6-bromo-8-cyclopentyl-2-(5-piperazin-1-yl-pyridin-2-ylamino)-8H-pyrido[2,3-d]pyrimidin-7-one hydrochloride as a pale yellow solid (0.254 g).
