Procedure

6-Bromo-8-cyclopentyl-2-methanesulfinyl-5-methyl-8H-pyrido[2,3-d]pyrimidin-7-one (1.0 g, 2.70 mmol) and 5-(2,6-dimethyl-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) to give 6-bromo-8-cyclopentyl-2-[5-(2,6-dimethyl-morpholin-4-yl )-pyridin-2-ylamino]-5-methyl-8H-pyrido[2,3-d]pyrimidin-7-one as a brown solid (0.358 g, 27.3%). MS (APCl) Calc'd for M+1: 513.2. Found: 513.1. Anal. Calc'd for C24H29BrN6O2: C, 56.14; H, 5.69; N, 16.37. Found; C, 55.90; H, 5.62; N, 16.10.
