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.
