(IV) Treatment of 3-nitro-1,8-naphthalic anhydride (I) with mercuric oxide and aqueous sodium acetate, and then with refluxing concentrated HCl provided a mixture of decarboxylation products (II) and (III). Condensation of this mixture with L-methionine methyl ester (IV) in the presence of dicyclohexylcarbodiimide and 1-hydroxybenzotriazole, followed by chromatographic separation of isomers, yielded the desired 6-nitronaphthalenecarboxamide (V). Further reduction of the nitro group with SnCl2 in ethanol gave amine (VI), which was reductively condensed with S-triphenylmethyl-N-Boc-cysteinal (VII) in the presence of sodium cyanoborohydride, acetic acid, and molecular sieves to afford (VIII). Then, hydrolysis of methyl ester with lithium hydroxide in THF-water gave acid (IX), and finally, deprotection of trityl and tert-butoxycarbonyl groups with an excess of trifluoroacetic acid in the presence of ethanedithiol provided the title compound as the trifluoroacetate salt.

(III) L-5,5-Dimethylthiazolidine-4-carboxylic acid (I) was protected as the N-Boc derivative (II) by treatment with Boc2O and subsequently coupled with L-methionine methyl ester (III) employing EDC and HOBt. The resulting Boc-dipeptide (IV) was then deprotected with trifluoroacetic acid to give (V). On the other hand, Boc-isoleucine (VI) was converted to the N-methoxy amide (VII) by condensation with N,O-dimethylhydroxylamine in the presence of O-benzotriazolyl tetramethyluronium hexafluorophosphate. Reduction of (VII) with LiAlH4 in cold Et2O produced the corresponding aldehyde (VIII). Reductive condensation of thiazolidine (V) with aldehyde (VIII) yielded adduct (IX). The Boc group of (IX) was then deprotected with trifluoroacetic acid to give (X).

(VI) 5-Bromo-2-furoic acid (I) was converted to the mixed anhydride with isobutyl chloroformate and then reduced to alcohol (II) using NaBH4. After formation of the sodium alkoxide of (II) with NaH, condensation with chloride (III) in the presence of 15-crown-5 provided ether (IV). Hydrolysis of the methyl ester of (IV), followed by coupling of the resulting carboxylic acid (V) with L-methionine methyl ester (VI) gave amide (VII). Further Suzuki coupling of (VII) with 4-chlorophenyl boronic acid (VIII) produced the aryl-substituted furan (IX). Finally, hydrolysis of the methionine methyl ester of (IX) with LiOH, followed by lyophilization furnished the corresponding lithium carboxylate salt.

(I) Amide (III) was prepared by acylation of L-methionine methyl ester (I) with 3-(chloromethyl)benzoyl chloride (II). Displacement of the halogen atom of (III) with LiN3 gave azide (IV), which was reduced to amine (V) by catalytic hydrogenation in the presence of Pd/C. Reductive coupling of (V) with protected imidazole-4-carboxaldehyde (VI) provided the (imidazolylmethyl)amine (VII), and a second reductive coupling of (VII) with benzaldehyde (VIII) furnished the trisubstituted amine (IX). The regioselective imidazole alkylation of (IX) with bromide (X), followed by trityl group deprotection with trifluoroacetic acid yielded (XI). Finally, the methyl ester group of (XI) was hydrolyzed with methanolic NaOH to afford the title carboxylic acid.

该中间体在本合成路线中的序号:
(VIII) Condensation of 3-aminopyridine (I) with benzaldehyde (II) in refluxing toluene with azeotropic removal of water produced imine (III), which was reduced to amine (IV) using ethanolic NaBH4. Subsequent alkylation of (IV) with methyl 4-bromomethyl-2-(2-methylphenyl)benzoate (V) in the presence of n-BuLi in cold THF yielded the tertiary amine (VI). Basic hydrolysis of the ester group of (VI), followed by EDC-promoted coupling of the resulting carboxylic acid (VII) with L-methionine methyl ester (VIII) afforded amide (IX). The title compound was finally obtained by saponification of the methyl ester group of (IX) by means of LiOH.

(VII) Palladium-catalyzed coupling of dimethyl iodoterephthalate (I) with 2-methylphenylboronic acid (II) furnished the biphenyl derivative (III). Regioselective ester hydrolysis of (III) under controlled conditions provided the mono acid (IV), which was further reduced to alcohol (V) using borane in THF. After hydrolysis of the remaining ester function of (V), the resulting carboxylic acid (VI) was coupled to L-methionine methyl ester (VII), yielding amide (VIII). Swern oxidation of the alcohol function of (VIII) gave aldehyde (IX). This was then subjected to a reductive amination with amine (X) in the presence of NaBH(OAc)3 to afford the secondary amine (XI). The methyl ester group of (XI) was finally hydrolyzed with LiOH.

(XII) Cyclohexylacetic acid (VII) was converted to acid chloride and then condensed with n-butyl amine to give amide (VIII). Reduction of (VIII) with LiAlH4 afforded secondary amine (IX), which was alkylated with bromide (VI) yielding amino ester (X). After basic hydrolysis of the ester group of (X), the resultant carboxylic acid (XI) was coupled with L-methionine methyl ester (XII) to produce amide (XIII). The methyl ester group of (XIII) was finally hydrolyzed by treatment with LiOH.
