合成路线:The acylation of aniline (I) with methanesulfonyl chloride (II) in pyridine gives the corresponding sulfonamide (III),which is submitted to a Friedel-Crafts condensation with succinic anhydride (IV) and AlCl3 in hot carbon disulfide to afford 4-[4-(methanesulfonyl)phenyl]-4-oxobutyric acid (V).The amidation of (V) with N-ethylheptylamine (VI) yields the corresponding amide (VII),which is finally reduced with LiAlH4 in THF and treated with an ethanolic solution of fumaric acid in order to precipitate the corresponding salt.
