The silylation of 8-aminooctanoic acid (I) with Tms-Cl in dichloromethane gives the disilylated compound (II), which is treated with 2-hydroxybenzoyl chloride (III) and TEA to yield the corresponding silylated amide (IV). Finally, this compound is desilylated with NaOH to afford the target sodium salt.

该中间体在本合成路线中的序号:(II)

Full protection of 8-aminooctanoic acid (I) with TMSCl in refluxing CH2Cl2 yields derivative (II), which is then coupled to acetylsalicyloyl chloride (III) by means of Et3N to provide compound (IV). Finally, the desired product is obtained by saponification of (IV) with NaOH. Alternatively, another route can be followed for the synthesis of the target compound: Curtius rearrangement of nonanedioic acid monomethyl ester (V) with DPPA and Et3N in toluene, followed by treatment with tert-BuOH, affords Boc-amino ester (VI), whose Boc group is then removed by means of HCl in dioxane to yield deprotected ester (VII). Coupling of (VII) with acetylsalicyloyl chloride (III) by means of Et3N in THF/DMF gives compound (VIII), which is finally saponified with NaOH.
