The condensation of 5(S)-(trityloxymethyl)-2-pyrrolidinone (I) with benzyl chloroformate (II) and BuLi in THF gives the carbamate (III), which is alkylated with tert-butyl 2-chloroacetate (IV) and LHMDS in THF to yield 2-[1-(benzyloxycarbonyl)-2-oxo-5(S)-(trityloxymethyl)pyrrolidin-2(S)-yl]acetic acid tert-butyl ester (V). The hydrogenation of (V) with H2 over Pd/C in hot tert-butanol affords 2-[5(S)-(hydroxymethyl)-2-oxopyrrolidin-2(S)-yl]acetic acid tert-butyl ester (VI), which is treated with MsCl and TEA in dichloromethane to provide the methanesulfonate (VII). The condensation of (VII) with 4'-hydroxybiphenyl-4-carbonitrile (VIII) by means of potassium tert-butoxide in DMF gives the adduct (IX), which by treatment with HCl in methanol and with ammonia in the same solvent yields 2-[5(S)-(4'-amidinobiphenyl-4-yloxymethyl)-2-oxopyrrolidin-3(S)-yl]acetic acid methyl ester (X). Finally, this compound is hydrolyzed with NaOH in methanol to afford the target acetic acid derivative.

Finally, this compound is condensed with methyl chloroformate (XI) by means of NaOH in dichloromethane to afford the target compound.

Alkylation of 4-cyano-4'-hydroxybiphenyl (I) with 1-bromo-3-chloropropane (II) yields the chloropropyl ether (III). This is then condensed with the mono-protected homopiperazine (IV) to furnish (V). Removal of the N-Boc group of (V) to afford amine (VI) is then accomplished by treatment with trifluoroacetic acid in CH2Cl2. Amine (VI) is subsequently coupled with N-Boc-D-thiazolylalanine (VII) in the presence of EDC/DMAP producing amide (VIII). (1,2)
