EXAMPLE 3 Preparation of 6-ACETVL-8-CVCLOPENTVI-5-METHYL-2- (5-PIPERAZIN-1- EL-PVRIDIN-2-YLAMINO)- 8H-PVRIDOR2, 3-DLPYRIMIDIN-7-ONE HVDROCHLORIDE Hydrogen chloride gas was bubbled into an ice-bath cooled solution of 4- {6- [8- CYCLOPENTYL-6- (1-ETHOXY-VINYL)-5-METHYL-7-OXO-7, 8-dihydro-pyrido [2, 3-D] idin-2-ylamino]- PYRIDIN-3-YL}-PIPERAZINE-1-CARBOXYLIC acid tert-butyl ester (4.50 g, 0.00783 mol, prepared as in Example 2) in DCM (100 mL). The resulting suspension was stoppered and stirred at RT overnight, then diluted with diethyl ether (200 mL). The solid was collected by filtration, washed with diethyl ether, and dried to give the hydrochloride salt of 6-acetyl-8-cyclopentyl-5- METHYL-2- (5-PIPERAZIN-1-YL-PYRIDIN-2-YLAMINO)-8H-PYRIDO [2, 3-d] pyrimidin-7-one as a yellow solid (4. 01 g, 92 %).
