  • Patent number: 11274096
    Abstract: The present disclosure relates to novel processes for the preparation of compounds of Formula I. Some of these compounds are useful as simulators of soluble guanylate cyclase (sGC). Others are useful intermediates towards the preparation of said simulators. These processes are amenable to large scale preparation and produce stable 3-(2-pyrimidinyl)pyrazoles of Formula I in high purity and yields. The present invention has the additional advantage of facile reaction conditions, amenable to scale up for large scale manufacturing. The disclosure also provides novel intermediates useful in the preparation of said compounds.
    Type: Grant

    Assignee: Cyclerion Therapeutics, Inc.
    Inventors: Debra Jane Wallace, Fenger Zhou, Yuguang Wang, Takashi Nakai, Vishnu Vardhan Reddy Karnati, Wayne C. Schairer, William Kissel, Song Xue, Ahmad Hashash
  • Publication number: 20220024909
    Abstract: The present disclosure relates to novel processes for the preparation of compounds of Formula I. Some of these compounds are useful as stimulators of soluble guanylate cyclase (sGC). Others are useful intermediates towards the preparation of said stimulators. These processes are amenable to large scale preparation and produce stable 3-(2-pyrimidinyl)pyrazoles of Formula I in high purity and yields. The present invention has the additional advantage of facile reaction conditions, amenable to scale up for large scale manufacturing. The disclosure also provides novel intermediates useful in the preparation of said compounds.
