Reaction Steps

8-Cyclopentyl-6-ethyl-2-methanesulfonyl-8H-pyrido[2,3-d]pyrimidin-7-one (0.115 g, 0.47 mmol) and 6′-amino-3,4,5,6-tetrahydro-2H-[1,3′]bipyridinyl-4-ol (0.117 g, 0.61 mmol) were combined in dry xylenes and heated at 140° C. under nitrogen overnight. The crude reaction mixture then was allowed to cool and diluted with CH2Cl2. A precipitate was collected by filtration and dried in vacuo to give 8-cyclopentyl-6-ethyl-2-(4-hydroxy-3,4,5,6-tetrahydro-2H-[1,3′]bipyridinyl-6′-ylamino)-8H-pyrido[2,3-d]pyrimidin-7-one (15 mg, 7%). MS (APCI); M++1: Calc'd, 435.2. Found 435.2.
