The dipeptide intermediate (XI) has been obtained as follows: The coupling of the two synthons (I) and (II) by means of K2CO3 and 18-C-6 in DMSO gives the diphenyl ether (III), which is reduced at its nitro group with H2 over Pd/C yielding the amine (IV). The treatment of (IV) with tert-butyl nitrite, HBF4 and Cu2O affords the phenol (V), which is methylated with MeI and K2CO3 to provide the corresponding methyl ether (VI). The protection of the primary alcohol of (VI) with benzyl bromide (A) and K2CO3 gives the benzyl ether (VII), which is deprotected at the Mem and trifluoroacetamido groups yielding the aminoethanol derivative (VIII). The condensation of (VIII) with the protected phenylalanine derivative (IX) by means of EDC and HOBT affords the corresponding amide (X), which is finally oxidized with Dess Martin periodinane (DMP) and NaClO2 to afford the desired dipeptide intermediate (XI).

The synthesis of intermediate (XI) as been performed as follows: The reaction of 3-benzyloxy-5-methoxystyrene (I) with K2OsO4(OH)4, (DHQ)2PHAL and BocNClNa gives the hydroxyethyl carbamate (II), which is protected with Mem-Cl, yielding (III). The reductive deprotection of (III) with H2 over Pd/C, followed by reaction with trifluoroacetic anhydride (TFAA), affords the amide (IV), which is condensed with the hydroxyethyl carbamate (V) (obtained by reaction of 3-fluoro-4-nitrostyrene (VI) with K2OsO4(OH)4, (DHQD)2PHAL and BocNClNa) by means of K2CO3, providing the diaryl ether (VII). The reduction of the nitro group of (VII) with H2 over Pd/C gives the corresponding amino group, which is converted into the phenol (IX) by reaction with tBu-ONO, BHF4, Cu2O and Cu(NO3)2. The methylation of the phenol (IX) with MeI and K2CO3 yields the corresponding ether (X), which is finally treated with K2CO3 to eliminate the trifluoroacetyl group, yielding the desired intermediate (XI).
