The synthesis and antiplatelet activity of substituted pyrazolyl piperidinederivatives (3a–n) are described. These compounds were synthesized by an improved ring opening reaction of 2‐arylidene quinuclidinone using hydrazine hydrate under mild conditions. They were characterized and screened for their in vitro antiplatelet profile in human platelet aggregation using adenosine diphosphate as agonist

5-(4-Chlorophenyl)-3-(1-(4-chlorobenzyl)piperidin-4-yl)pyrazole (3) was identified from screening of the Merck sample collection as a humandopamineD4 (hD4) receptor ligand with moderate affinity (61 nM) and 4-fold selectivity over human D2 (hD2) receptors. Four separate parts of the molecule have been examined systematically to explore structure-activity relationships with respect to hD4 affinity
