ABSTRACT
@#To strengthen the quality control of palbociclib, three related substances were separated from the bulk drug. These substances were identified as 8-cyclopentyl-5-methyl-2-((5-(piperazin-1-yl)pyridin-2-yl)amino)pyrido [2, 3-d] pyrimidin-7(8H)-one(A), 8-cyclopentyl-5-methyl-2-((5-(piperazin-1-yl)pyridine-2-yl)amino)-6-vinylpyrido [2, 3-d] pyrimidin-7(8H)-one(B), tert-butyl4-(6-((6-acetyl-8-cyclopentyl-5-methyl-7-oxo-7, 8-dihydropyrido [2, 3-d] pyrimidin-2-yl)amino)pyridin-3-yl)piperazi-ne-1-carboxylate(C). Based on the structures of the impurities, the possible routes to them were discussed, and their structures were elucidated by 1H NMR and MS.
