(V) Alkylation of 5-methoxytetralone (I) with n-butyl iodide in the presence of lithium diisopropylamide (LDA) in dimethoxyethane afforded a mixture of mono- (II) and dialkylated (III) compounds that were separated by column chromatography. Hydrolysis of methoxy group of (III) by treatment with AlBr3 in refluxing benzene yielded phenol (IV), which was converted to ether (VI) by treatment with 2-(chloromethyl)quinoline (V) and K2CO3. The reduction of ketone (VI) with NaBH4 in MeOH provided racemic alcohol (VII). Resolution of racemate (VII) was performed by esterification with (S)-O-methylmandeloyl chloride (VIII), followed by chromatographic separation of the diastereomeric mixture. Then, basic hydrolysis of pure diastereomer (IX) provided the (+)-enantiomer. Alternatively, asymmetric reduction of tetralone (VI) with LiAlH4 in cold THF in the presence of the chiral auxiliary (S)-4-anilino-3-methylamino-1-butanol (X) or (S)-2-amino-3-methyl-1,1-diphenyl-1-butanol (XI) afforded (+)-alcohol (respectively).

(V) The reaction of phenol (I) with 4-oxopentanoic acid (II) by means of H2SO4 gives 4,4-bis(4-hydroxyphenyl)pentanoic acid (III), which is esterified with MeOH and H2SO4 to yield the methyl pentanoate (IV). The condensation of (IV) with 2-(chloromethyl)quinoline (V) by means of K2CO3 in DMF affords the adduct (VI), which is finally hydrolyzed with NaOH in methanol/dioxane to provide the target sodium salt.
Alternatively, the intermediate methyl pentanoate (IV) can also be obtained by direct condensation of phenol (I) with methyl 4-oxopentanoate (VII) by means of H2SO4 as before.

(II) Condensation of 4-hydroxyphenylethanol (I) with 2-(chloromethyl)quinoline (II) in ethanolic KOH provided ether (III). The free hydroxyl group of (III) was then converted to the corresponding mesylate (IV) by treatment with methanesulfonyl chloride and Et3N. Alkylation of 11-(4-piperidinylidene)-6,11-dihydro-5H-imidazo[2,1-b][3]benzazepine-3-methanol (V) with mesylate (IV) in the presence of NaHCO3 gave adduct (VI). The primary alcohol of (VI) was oxidized to aldehyde (VII) using MnO2 in CH2Cl2. Finally, aldehyde (VII) was further oxidized to the title methyl ester by means of MnO2 in the presence of sodium cyanate in HOAc-MeOH.

(I) The alkylation of N-formylpiperazine (II) with 2-(chloromethyl)quinoline (I) produced the disubstituted piperazine (III). The formyl group of (III) was then cleaved by means of H2SO4 in boiling EtOH, yielding quinolylmethylpiperazine (IV). Subsequent alkylation of (IV) with 1-bromo-3-chloropropane (V) afforded the chloropropyl derivative (VI). This was finally condensed with 7-hydroxybenzothiazinone (VII) in the presence of K2CO3 and a phase-transfer catalyst to furnish the title compound.

(IV) Ether cleavage of 4-(4-methoxyphenylsulfanyl)benzoic acid (I) with pyridine hydrochloride at 220 C provided phenol derivative (II). Subsequent esterification of (II) with methanol and sulfuric acid gave methyl ester (III). The quinolylmethyl ether (V) was then prepared by alkylation of (III) with 2-(chloromethyl)quinoline (IV) in the presence of K2CO3 and KI. Finally, the methyl ester group of (V) was hydrolyzed employing a hydroalcoholic solution of KOH.
