该中间体在本合成路线中的序号：(II)Coupling of N-alpha-Fmoc-N-epsilon-Boc-lysine (I) to 7-amino-4-methylcoumarin (II) by means of DCC produces the lysine amide (III). After acidic cleavage of the N-Boc protecting group of (III), the resultant primary amine (IV) is attached to chlorotrityl resin to produce (V). The Fmoc group of (V) is then removed with piperidine in DMF, yielding the lysinamide-bound resin (VI). Further coupling with N-Fmoc-cyclohexylalanine (VII) employing TBTU/HOAt furnishes the dipeptide amide resin (VIII). The title compound is finally cleaved from the solid support by means of trifluoroacetic acid in CH2Cl2.
