   The application of continuous methods in the synthesis of active pharmaceutical ingredients continues to receive significant attention in the academic as well as the industrial research communities. One of the major advantages of continuous methods is the ability to safely access kinetic synthons...

   A continuous synthesis line was developed integrating different common reaction steps namely nitration, substitution and hydrogenation. Mesalazine as model drug substance was produced from 2-chlorobenzoic acid in continuous flow mode. A multi-instrument PAT strategy was implemented to equip the...

3. An expeditious synthesis of imatinib and analogues utilising flow chemistry methods

   A flow-based route to imatinib, the API of Gleevec, was developed and the general procedure then used to generate a number of analogues which were screened for biological activity against Abl1. The flow synthesis required minimal manual intervention and was achieved despite the poor solubility of...
