Procedure

To a solution of 8-cyclopentyl-6-(1-ethoxy-vinyl)-2-(4-hydroxy-3,4,5,6-tetrahydro-2H-[1,3′]bipyridinyl-6′-ylamino)-5-methyl-8H-pyrido[2,3-d]pyrimidin-7-one (255 mg, 0.52 mmol) in chloroform (2 mL) was added hydrogen chloride (2 M ethereal solution, 5.0 mL, 10.0 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-2-(4-hydroxy-3,4,5,6-tetrahydro-2H-[1,3′]bipyridinyl-6′-ylamino)-5-methyl-8H-pyrido[2,3-d]pyrimidin-7-one (213 mg, 0.46 mmol). MS (APCI+) 463 (M+1, 100); 1HNMR δ(400 MHz, DMSO-d6) 10.90 (br, 1H), 9.07 (s, 1H), 8.19 (s, 1H), 7.91 (br, 2H), 5.91-5.89 (m, 1H), 3.77 (br, 1H), 3.62 (br, 2H), 3.07 (br, 2H), 2.58 (s, 3H), 2.40 (s, 3H), 2.30 (br, 2H), 1.98-1.86 (m, 5H), 1.65 (br, 4H); Anal. Calc'd for C25H30N6O3, 1.76C3H8O1, 0.36CHCl3: C, 60.20; H, 7.33; N, 13.75. Found: C, 60.48; H, 6.97; N, 13.35.
