A series of benzodioxanylpiperazine derivatives possessing a 4-aryl amide substituent was prepared and evaluated for 5-HT_1A affinity and functional antagonist activity in vitro and in vivo. All of the compounds in this series possessed high affinity for the human 5-HT_1A receptor and many displayed potent antagonist activity in vitro and varying degrees of intrinsic activity in vivo. Compound 11c (Lecozotan) was selected for further development and is currently in clinical trials.
