Abstract

A practical and efficient synthesis of the FLAP inhibitor 1 was developed addressing multiple scale-up and safety concerns posed by the established synthesis and utilized a resolution strategy (replacing supercritical fluid chromatography (SFC) separation) for expedient access to the key structural component of 1: the challenging chiral quaternary center. Also highlighted are in situ IR monitoring, condensation to form the 1,2,4-oxadiazole ring, and an efficient Suzuki-Miyaura coupling.
