The intermediate 5-fluoro-3-[3-(1-piperazinyl)propyl]-1H-indole (V) has been obtained as follows: a) The condensation of 5-fluoro-1H-indole (VIII) with acrylic acid (IX) by means of acetic anhydride gives 3-(1H-indol-5-yl)propionic acid (X), which is reduced with LiAlH4 to 3-(1H-indol-5-yl)-1-propanol (XI). The tosylation of (XI) with tosyl chloride yields the tosylate (XII), which is condensed with 1-benzylpiperazine (XIII) in refluxing butyl acetate affording 3-[3-(4-benzylpiperazin-1-yl)propyl]-5-fluoro-1H-indole (XIV). Finally, this compound is debenzylated by hydrogenation with H2 over Pd/C yielding the target intermediate (V). b) The tosylate intermediate (XII) can also be condensed with ethyl piperazine-1-carboxylate (XVII) in refluxing butyl acetate giving 4-[3-(5-fluoro-1H-indol-3-yl)propyl]piperazine-1-carboxylic acid ethyl ester (XVIII), which is then decarboxylated with NaOH to the target intermediate (V). The intermediate 3-(1H-indol-5-yl)-1-propanol (XI) can also be obtained by direct cyclization of 4-fluorophenylhydrazine (XV) with dihydropyran (XVI) in hot propyleneglycol.
