  1. Optimization and Scale-Up of the Continuous Flow Acetylation and Nitration of 4-Fluoro-2-methoxyaniline to Prepare a Key Building Block of Osimertinib

    Contributor(s):: Köckinger, Manuel, Wyler, Benjamin, Aellig, Christof, Roberge, Dominique M., Hone, Christopher A., Kappe, C. Oliver

    The development of a scalable telescoped continuous flow procedure for the acetylation and nitration of 4-fluoro-2-methoxyaniline is described. A subsequent batch deprotection then affords 4-fluoro-2-methoxy-5-nitroaniline, a key building block in the synthesis of osimertinib, a third-generation...

  2. Continuous Multiphase Flow Nitration and Cryogenic Flow Formylation: Enabling Process Development and Manufacturing of Pharmaceutical Intermediates

    Contributor(s):: Cardinal-David, Benoit, Harper, Kaid C., Verma, Anuj, Hanna, David, Caspi, Daniel D., Vitale, Christopher, Bien, Jeffrey T., Wang, Zhe, Diwan, Moiz

    Manufacturing API and pharmaceutical intermediates requires the development of scalable, safe, and environmentally friendly processes. Reactions with high exothermicity or otherwise hazardous in nature, as well as reactions involving the formation of unstable intermediates, can benefit from...
