Procedure

4-{6-[8-Cyclopentyl-6-(1-ethoxy-vinyl)-5-methyl-7-oxo-7,8-dihydro-pyrido[2,3-d]pyrimidin-2-ylamino]-pyridin-3-yl}-2,2-dimethyl-piperazine-1-carboxylic acid tert-butyl ester (0.250 g, 0.414 mmol) was dissolved in dichloromethane (3 mL) to which 2 N HCl in diethyl ether (3 mL) was added and the mixture was stirred at room temperature for 16 hours. The solvent was evaporated and the solid was dried in a vacuum oven for 24 hours at 50° C. to give 6-acetyl-8-cyclopentyl-2-[5-(3,5-dimethyl-piperazin-1-yl)-pyridin-2-ylamino]-5-methyl-8H-pyrido[2,3-d]pyrimidin-7-one hydrochloride salt as a yellow solid (0.120 g, 38.1%). 1H NMR δ(400 MHz, DMSO-d6) 9.51 (m, 2H), 9.0 (m, 1H), 8.97 (s, 1H), 8.08 (d, J=2.7 Hz, 1H), 7.84 (d, J=9.3 Hz, 1H), 7.78 (m, 1H), 5.80 (m, 1H), 3.35 (d, J=11.5 Hz, 2H), 3.35 (m, 2H), 2.75 (dd, J=12.2, 2H), 2.40 (s, 3H), 2.30 (s, 3H), 2.19 (m, 2H), 1.88 (m, 2H), 1.76 (m, 2H), 1.57 (m, 2H), 1.29 (d, J=6.6 Hz, 6H). MS (APCI); M++1: Calc'd, 476.3. Found 476.1. Anal. Calc'd for C26H33N7O22.70HCl, 0.10H2O: C, 54.23, H, 6.28, N, 17.03. Found: C, 54.60; H, 6.68; N, 16.57.
