合成路线:Condensation of 5-nitroindole (I) with 1-methyl-4-piperidone (II) in the presence of KOH produced tetrahydropyridinyl indole (III).Subsequent catalytic hydrogenation of (III) over Pd/C gave the 5-amino-3-piperidinylindole (VI).In a related procedure,5-aminoindole (IV) was condensed with piperidone (II),and the resulting tetrahydropyridine (V) was hydrogenated to yield (VI).Aminoindole (VI) was finally condensed with 4-fluorobenzoyl chloride (VII) to produce the corresponding amide,which was isolated as the fumarate salt.
合成路线:Acylation of 4-nitroaniline (I) with 4-fluorobenzoyl chloride (II) affords benzanilide (III).Catalytic hydrogenation of the nitro group of (III) employing Pt/C then gives amine (IV).Diazotization of (IV),followed by reduction with SnCl2 leads to hydrazine (V).Reaction of 5-chloro-2-pentanone (VI) with dimethylamine yields the amino ketone (VII).Finally,the title compound is obtained by Fisher indole synthesis from aryl hydrazine (V) and ketone (VII) under acidic conditions.
