The title peptide was prepared by solid-phase synthesis using a p-methylbenzhydrylamine resin (II). Coupling of Boc-lysine(2-ClZ) (I) to the resin (II) using diisopropylcarbodiimide (DIC) and 1-hydroxybenzotriazole (HOBt) afforded the amide resin (III). The N-Boc group was then selectively deprotected with trifluoroacetic acid in CH2Cl2, yielding resin (IV). To this were sequentially attached the protected amino acids: Boc-phenylalanine (V), Boc-D-arginine(Ts) (VII) and Boc-2',6'-dimethyltyrosine(Boc) (IX) employing DIC/HOBt and then Boc deprotection with trifluoroacetic acid to provide the peptide resins (VI), (VIII) and (X), respectively. Finally, the desired peptide amide was deprotected and cleaved from the resin (X) by treatment with HF and anisole.
