  • Publication number: 20230339928
    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.

  • Publication number: 20230190662
    Abstract: Methods and formulations of reducing one or more symptoms of gastroesophageal reflux disease (GERD) in a human patient with symptomatic GERD not completely responsive to proton pump inhibitors (PPIs). The patient is administered a therapeutically effective amount of an enteric coated gastro-retentive oral dosage form in the form of a tablet of a bile acid sequestrant dispersed in a polymeric matrix consisting essentially of poly(alkylene)oxide and one or more filler or compressing agent such that the patient experiences a clinically meaningful reduction in one or more symptoms of GERD.
