Starting from a known linear route and a proposed convergent route, we have successfully developed a new hybrid convergent route to MIV-150 that takes advantage of the robust chemistry for the preparation of a fluoroketal and the stereospecific Negishi coupling of an iodocyclopropane moiety to a benzene ring. Stereoselective beta- and cis-iodination chemistry was developed for the preparation of an enantiomerically pure iodocyclopropanecarboxylate. Following the Negishi coupling, proven chemistry from the linear route was incorporated, thus ensuring a similar high-purity profile for the final active pharmaceutical ingredient (API). In addition, we have prepared and evaluated a series of basic inorganic and organic MIV-150 salts that have drastically increased water solubility over the parent compound.
