Description

6-Chloro-2-methylpyrido[3,4-d]pyrimidin-4(1H)-one features a fused pyridopyrimidinone core with strategic chlorine and methyl substitutions. This electron-deficient heterocycle integrates readily into medicinal chemistry scaffolds, offering enhanced metabolic stability and favorable binding interactions in kinase-targeted drug discovery.

Application

6-Chloro-2-methylpyrido[3,4-d]pyrimidin-4(1H)-one serves as a versatile building block for purine-derived scaffolds in medicinal chemistry. The chloro group at C6 enables nucleophilic substitution reactions, while the 2-methyl and lactam functionalities provide orthogonal reactivity for downstream functionalization. Its bench-stable crystalline form facilitates handling and purification, making it well-suited for modular synthesis of kinase inhibitors and other bioactive heterocycles.
