How is (E)-2-(1-(2-Cyclopropyl-1-(2-fluorophenyl)-2-oxoethyl)-4-mercaptopiperidin-3-ylidene)acetic acid (CAS: 239466-74-1) typically synthesized?

This compound is synthesized using a multistep process involving the formation of a key intermediate, which is then reacted with acetic anhydride to form the final product. The synthesis typically involves protecting groups and selective functional group transformations. Catalysts and reagents are chosen to ensure high selectivity and yield. The process is carried out under an inert atmosphere to prevent side reactions.
