Abstract

Synthesis of arylpiperideines 3a‐3d and arylpiperidines 4a‐4d as analogs of a well known serotonin ligand 1‐(3‐chlorophenyl)piperazine is reported. Starting aryllithium derivatives were treated with 1‐methyl‐piperdin‐4‐one to provide the corresponding hydroxy derivatives 6a and 6b. N‐Methylpiperideine derivatives 3a and 3c were obtained by their dehydration while the corresponding N‐unsubstituted compounds 3b and 3d were prepared indirectly by a three‐step procedure. Hydrogenation of piperideine 3a provided the corresponding piperidine derivative 4a which after demethylation yielded 4b. Similar 4‐pyridyl derivatives 4c and 4d were prepared by a similar strategy via the corresponding methoxy derivatives.
