実験手順

6-Bromo-8-cyclopentyl-2-methanesulfinyl-5-methyl-8H-pyrido[2,3-d]pyrimidin-7-one (1.0 g, 2.70 mmol) and 5-morpholin-4-yl-pyridin-2-ylamine (0.668 g, 3.73 mmol) were heated to reflux in toluene (10 mL) for 16 hours. The reaction mixture was cooled to room temperature and the precipitate that formed was collected by filtration and washed on the funnel with toluene (3×10 mL). The solid obtained was refluxed in ethyl acetate (15 mL), cooled and filtered to give 6-bromo-8-cyclopentyl-5-methyl-2-(5-morpholin-4-yl-pyridin-2-ylamino)-8H-pyrido[2,3-d]pyrimidin-7-one as a dark brown-gray solid (0.350 g, 26.7%). 1H NMR δ(400 MHz, CDCl3) 8.78 (s, 1H), 8.17 (d, J=9.0 Hz, 1H), 8.02 (d, J=2.7 Hz, 1H), 7.97 (s, 1H), 7.32 (dd, J=2.9, 9.0 Hz, 1H), 5.99 (m, 1H), 3.89 (m, 4H), 3.16 (m, 4H), 2.61 (s, 3H), 2.30 (m, 2H), 2.10 (m, 2H), 1.88 (m, 2H), 1.68 (m, 2H).
