Synthesis of benzo[b]thiophene carboxamides connected to 4-arylpiperazines through a benzylic spacer: Potential Ligands with 5-HT1A binding affinity

Abstract
New benzothiophene arylpiperazine derivatives 8 (a-f) were synthesized as potential serotoninergic agents with 5-HT1A receptor affinity. Preparation of the derivatives was performed by treating N-[2-(chloromethyl)phenyl]-4,7-dimethoxybenzo[b]thiophene-2-carboxamide (7) with a series of substituted 4-arylpiperazines.
