2-Fluoro-5-((3-oxoisobenzofuran-1(3H)-ylidene)methyl)benzonitrile

It provides part of the core structure, specifically incorporating the benzonitrile and phthalide/phthalazinone precursor elements, which are then further modified (e.g., via reactions like Negishi coupling) to form the final complex Olaparib molecule. 2-Fluoro-5-((3-oxoisobenzofuran-1(3H)-ylidene)methyl)benzonitrile (CAS 763114-25-6) is a crucial intermediate or building block in the multi-step synthesis of Olaparib (Lynparza), a targeted cancer drug (PARP inhibitor).
