Quantitative data
• An indigenous synthetic process route/technology for the development of generic Nusinersen.
• Innovative Elements of the Project: Improved synthesis of 2’-O-MOE phosphoramidite monomers through appropriate modification ofreported procedures.
• Shortened solid phase synthesis cycle by avoiding a separate capping step; achieving sulfurizationand capping in the same step through re-circulation of reagents.
