実験手順

To a solution of 8-cyclopentyl-6-(1-ethoxy-vinyl)-5-methyl-2-[5-(4-methyl-piperazin-1-yl)-pyridin-2-ylamino]-8H-pyrido[2,3-d]pyrimidin-7-one (237 mg, 0.48 mmol) in chloroform (5 ml) was added hydrogen chloride (2 M ethereal solution, 2.0 ml, 4.0 mmol). The reaction mixture was stirred at RT for 12 h. The solvents were evaporated and the residue was dissolved in ethanol. The ethanol was evaporated to give 6-acetyl-8-cyclopentyl-5-methyl-2-[5-(4-methyl-piperazin-1-yl)-pyridin-2-ylamino]-8H-pyrido[2,3-d]pyrimidin-7-one (239 mg, 0.52 mmol). MS (APCI+) 462 (M+1, 100); 1H NMR δ(400 MHz, DMSOd6) 10.83 (m, 2H), 9.00 (s, 1H), 8.1 (m, 1H), 7.88-7.82 (m, 2H), 5.89-5.80 (m, 1H), 3.88-3.85 (m, 2H), 3.54-3.51 (m, 2H), 3.23-3.11 (m, 4H), 2.83-2.82 (m, 3H), 2.43 (s, 3H), 2.34 (s, 3H), 2.23-2.11 (m, 2H), 1.93 (br, 2H), 1.81-1.77 (m, 2H), 1.60-1.59 (m, 2H); Anal.
