Abstract
  • Janus Kinase 1 (JAK1) inhibitor 1 is being developed between GlaxoSmithKline(GSK) and Galapagos for the treatment of systemic lupus erythematosus (SLE). Themedicinal chemistry route to 1 has been scaled up to provide kilogram quantities of 1for clinical trials. A new sustainable route to 1 is required to fund larger clinicalstudies and enable commercial manufacture.A new route was identified to prepare 1 using a Suzuki-Miyaura coupling in the finalsynthetic step. For the new route to be carried out in the pilot plant, it was necessaryto develop the final synthetic step to control palladium and impurity levels in orderfor 1 to be prepared in acceptable quality for clinical use. The new Suzuki-Miyauracoupling has been scaled up using an 45 Kg input of 149 preparing a total of 165 Kg1 containing <10ppm Pd and all impurities within specification.Metabolism of drug substance 1 has been investigated in order to develop 1 into amedicine. The synthesis of metabolites 157 and 167 was carried out to provideanalytical markers for a clinical study.
