合成路线:The cyclization of p-fluorophenylhydrazine (I) with 1-carbethoxy-4-piperidinone (II) in refluxing ethanol gives 2-carbethoxy-8-fluoro-1,2,3,4-tetrahydro-gamma-carboline (III),which is arylated with p-fluorobromobenzene (IV),by means of Na2CO3 - Cu2Br2 in N-methyl-2-pyrrolidinone heated at 200 C to yield 2-carbethoxy-8-fluoro-5-(p-fluorophenyl)-1,2,3,4-tetrahydro-gamma-carboline (V).The hydrolytic decarboxylation of (V) with KOH in refluxing ethanol affords 8-fluoro-5-(p-fluorophenyl)-1,2,3,4-tetrahydro-gamma-carboline (VI),which is alkylated with p-fluoro-gamma-bromobutyrophenone (VII) by means of Na2CO3 in hot DMF to give 8-fluoro-5-(p-fluorophenyl)-2-[4-(p-fluorophenyl)-4-oxobutyl]-1,2,3,4-tetrahydro-gamma-carboline (VIII).Finally this compound is reduced with NaBH4 in ethanol - THF

合成路线:The chlorination of N,N-bis(4-fluorophenyl)urea (I) gives N,N-bis(4-fluorophenyl)-N?chlorourea (II),which by reaction with sodium methoxide is converted into N,N-bis(4-fluorophenyl)-N-(methoxycarbony)hydrazine (III).Hydrolytic decarboxylation of (III) affords N,N-bis(4-fluorophenyl)hydrazine (IV),which is cyclocondensed with N-benzoyl-4-piperidone (V) yielding 8-fluoro-5-(4-fluorophenyl)-1,2,3,4-tetrahydro-gamma-carboline (VI).Finally this compound is condensed with 5-(4-fluorophenyl)-2-hydroxytetrahydrofuran (VII).
