Title compound was prepared by two related ways: N-(Benzyloxycarbonyl)-L-tryptofanol (I) was deprotected by hydrogenolysis in the presence of Pd/C. The resulting tryptofanol (II) was then coupled with N-(benzyloxycarbonyl)-L-isoleucine (III), using 1-(3-diethylaminopropyl)-3-ethylcarbodiimide.HCl (EDC) and 1-hydroxybenzotriazole (HOBt) to provide (IV). Subsequent hydrogenolytic deprotection gave amine (V), which was condensed with 1-naphthalenylsulfonyl chloride (VI) in the presence of 4-(dimethylamino)pyridine to afford sulfonamide (VII). Finally, oxidation with DMSO in the presence of SO3-pyridine complex yielded the aldehyde.
