The peptide moiety (XVII) was prepared by solid-phase synthesis in a peptide synthesizer starting from Boc-Leu-PAM resin (I). Removal of the Boc protecting group of (I) was effected by treatment with trifluoroacetic acid in CH2Cl2. To the deprotected Leu-resin (II) were sequentially incorporated the following amino acids: N-Fmoc-L-serine(O-t-Bu) (III), N-Fmoc-L-glutamine(Trt) (V), N-Fmoc-L-cyclohexylglycine (VII), again Fmoc-L-serine(O-t-Bu) (III), and N-Fmoc-L-alanine (X) using DCC and HOBt activation in N-methyl-2-pyrrolidinone, each followed by an Fmoc deprotection cycle with piperidine in DMF. The peptide resins (IV), (VI), (VIII), (IX) and (XI) were in turn obtained.
