実験手順

8-Cyclopentyl-6-ethoxymethyl-2-methanesulfinyl-8H-pyrido[2,3-d]pyrimidin-7-one (0.60 g, 1.79 mmol) and 3,4,5,6-tetrahydro-2H-[1,3′]bipyridinyl-6′-ylamine (0.438 g, 2.47 mmol) were heated to reflux in toluene (6 mL) for 16 hours. The reaction mixture was cooled to room temperature and the precipitate that formed was filtered off and washed with toluene (2×4 mL) to give 8-cyclopentyl-6-ethoxymethyl-2-(3,4,5,6-tetrahydro-2H-[1,3′]bipyridinyl-6′-ylamino)-8H-pyrido[2,3-d]pyrimidin-7-one (0.122 g, 15.2%). MS (APCI) Calc'd for M+1: 449.3. Found: 449.3. Anal. Calc'd for C25H32N6O2: C, 66.94; H, 7.19; N, 18.74. Found: C, 66.72; H, 7.13; N, 18.57.
