(IV) The reductocondensation of piperidine (I) with 3-hydroxybenzaldehyde (II) by means of sodium borohydride in ethanol gives 3-(1-piperidylmethyl)phenol (III), which is then condensed with N-(3-bromopropyl)phthalimide (IV) by means of NaH in DMF yielding N-[3-[3-(1-piperidylmethyl)phenoxy]propyl]phthalimide (V). The hydrolysis of (V) with hydrazine in ethanol affords 3-[3-(1-piperidylmethyl)phenoxy]propylamine (VI), which is acylated with hydroxyacetic acid (VII) at 200 C giving N-[3-[3-(1-piperidylmethyl)phenoxy]propyl]hydroxyacetamide (VIII). Finally, this compound is acetylated with acetic anhydride at 100 C.

(X) A new synthesis of MKC-242 has been described:
The tosylation of 2,2-dimethyl-1,3-dioxolane-4(R)-methanol (I) with tosyl chloride in pyridine gives the expected tosylate (II), which is condensed with pyrocatechol monobenzyl ether (III) by means of NaH in N-methylpyrrolidone (NMP) yielding 4(S)-(2-benzyloxyphenoxymethyl)-2,2-dimethyl-1,3-dioxolane (IV). The hydrolysis of the dioxolane ring with hot acetic acid affords the diol (V), which is tosylated with tosyl chloride, triethylamine and dimethylaminopyridine (DMAP) in dichloromethane to give the ditosylate (VI). The debenzylation of (VI) with H2 over Pd/C in methanol/ethyl acetate yields the phenol (VII), which is cyclized by means of K2CO3 in NMP affording 2(R)-(tosyloxymethyl)-1,4-benzodioxane (VIII). Finally, this compound is condensed with 3-(1,3-benzodioxol-5-yloxy)propylamine (IX) by means of ethyl diisopropylamine in NMP.
The amine (IX) used as second starting compound has been obtained as follows: The condensation of N-(3-bromopropyl)phthalimide (X) with 5-hydroxy-1,3-benzodioxole (XI) by means of NaH in hot NMP gives N-[3-(1,3-benzodioxol-5-yloxy)propyl]phthalimide (XII), which is then treated with hydrazine in refluxing methanol to obtain amine (IX).

(II) The alkylation of 3-hydroxybenzaldehyde (I) with N-(3-bromopropyl)phthalimide (II) in the presence of NaOMe leads to 3-(phthalimidopropoxy)benzaldehyde (III). The reductive alkylation of piperidine with aldehyde (III) in the presence of formic acid gives N-[3-[3-(1-piperidinylmethyl)phenoxy]propyl]phthalimide (IV), which is converted to N-[3-[3-(1-piperidinylmethyl)phenoxy]propyl]amine (V) by treatment with 6N HCl.

(II) OP C-33509 has been obtained by coupling imidazolecarboxamide (VI) with amine (IX) in refluxing CHCl3.
The intermediates (VI) and (IX) have been obtained as follows:
1) Alkylation of 6-hydroxycarbostyril (I) with N-(3-bromopropyl)- phthalimide (II) in the presence of K2CO3 in DMF furnished the phthalimidopropyl ether (III). Subsequent hydrazinolysis of the phthalimide in refluxing EtOH provided the primary amine (IV). Then, the imidazolecarboxamide (VI) was obtained by treating amine (IV) with 1,1'-carbonyldiimidazole (V) and two equivalents of imidazole in DMSO.
2) Ring opening of 1,2 epoxycyclohexane (VII) with cyclopropylamine (VIII) gave the racemic trans aminoalcohol. Resolution of enantiomers (IX) and (X) was accomplished by esterification with (S)-mandelic acid (XI), followed by chromatographic separation of the diastereomeric esters. Hydrolysis of the desired ester (XII) then provided optically pure aminoalcohol (IX). Finally, the target urea derivative was obtained by coupling imidazolyl urea (VI) with amine (IX) in refluxing chloroform.

(XVIII) Addition of 4-fluorophenylmagnesium bromide (XIII) to 1-benzyl-4-piperidinone (XII) afforded carbinol (XIV), which was dehydrated to the tetrahydropyridine (XV) by treatment with p-toluenesulfonic acid in refluxing toluene. Hydrogenation of the olefin (XV) with concomitant benzyl group hydrogenolysis gave 4-(4-fluorophenyl)piperidine (XVI) (1). This compound was also obtained by catalytic hydrogenation of the commercially available 4-(4-fluorophenyl)-1,2,3,6-tetrahydropyridine (XVII). Alkylation of piperidine (XVI) with N-(3-bromopropyl)phthalimide (XVIII) provided adduct (XIX), which was subjected to hydrazinolysis in refluxing MeOH to furnish the primary amine (XX). Deprotonation of oxazolidine (IX) with n-butyllithium in THF at -78 C, followed by condensation with p-nitrophenyl chloroformate, gave the p-nitrophenoxycarbonyl derivative (XXI). This was finally coupled with amine (XX) to furnish the title carboxamide.

(II) The alkylation of 4-methylimidazole (I) with N-(3-bromopropyl)phthalimide (II) produced a mixture of N-alkylated regioisomers (III) and (IV). After selective derivatization of the undesired 5-methyl isomer (III) with trityl chloride, the 4-methyl derivative was isolated by flash chromatography and subsequently subjected to phthaloyl group hydrazinolysis to yield amine (V). Reductive condensation of amine (V) with benzaldehyde (VI) in the presence of NaBH4 afforded the N-benzyl amine (VII).
