For R&D scientists engaged in pharmaceutical discovery and development, a deep understanding of synthetic pathways and the critical intermediates involved is fundamental. Apixaban, a highly effective direct factor Xa inhibitor, represents a significant advancement in anticoagulant therapy. Its synthesis is a complex process that relies on the precise assembly of specialized molecular fragments. Among these, Ethyl 1-(4-Methoxyphenyl)-7-oxo-6-[4-(2-oxopiperidin-1-yl)phenyl]-4,5,6,7-tetrahydro-1H-pyrazolo[3,4-c]pyridine-3-carboxylate (CAS: 503614-91-3) plays an indispensable role.

This compound, a sophisticated heterocyclic molecule, acts as a key precursor, embodying a significant portion of the final Apixaban structure. Its chemical name itself hints at the complexity of its structure, featuring a pyrazolopyridine core substituted with methoxyphenyl and oxopiperidinyl phenyl groups, along with an ethyl ester functionality. The successful synthesis and purification of this intermediate are critical for achieving the desired final product with high yield and purity. R&D scientists often require this compound for various purposes: validating synthesis routes, exploring structural analogues, or ensuring the availability of high-quality reference standards.
