The earlier reported syntheses of rufinamide had encountered challenges in isolating by-products from the mother liquor. In this work, the impurities were synthesized via the retrosynthesis route to serve as reference samples for assessing the purity level of drugs. These impurities, characterized by the presence of N-group and azole derivatives, find wide-range applications in academic and industrial settings, including organic synthesis, drug discovery, polymer chemistry, chemical biology, and supramolecular chemistry. The primary objective of this synthesis was to propose a reliable and pragmatic method for producing rufinamide and its impurities to address diverse scientific and industrial requirements.
