合成路线1
该中间体在本合成路线中的序号:(V)Alkylation of diethyl acetamidomalonate (I) with 1-bromodecane (II) affords malonate (III). Subsequent hydrolysis and decarboxylation of (III) under acidic conditions leads to 2-aminododecanoic acid (IV). This is then protected as the N-Boc derivative (V) upon treatment with Boc2O and NaOH

合成路线2
该中间体在本合成路线中的序号:(V)The protected peptide-bound resin (VI) is prepared by solid-phase synthesis on a p-methylbenzhydrylamine resin, using HBTU/DIEA activation. Coupling of 2-(Boc-amino)dodecanoic acid (V) to the peptide resin (VI) by means of HBTU affords amide (VII). The DNP protecting groups of the histidine residues of (VII) are subsequently removed by treatment with 2-mercaptoethanol to provide (VIII). Further acidic cleavage of the N-terminal Boc group of (VIII) with trifluoroacetic acid leads to resin (IX). The linear peptide (X) is then cleaved from the resin by treatment with liquid (HF) in the presence of p-thiocresol
