A series of 4'-substituted phenyl-4-piperidinylmethanol and benzoyl-4-piperidine derivatives was synthesized as potential novel serotonin 5-HT2A receptor ligands that can be radiolabeled for in vivo brain imaging. Compounds were prepared by alkylation of 4-substituted benzoyl-4-piperidine with an iodo- or fluoro-substituted phenylalkyl halide followed by reduction with sodium borohydride. Potency of
