Abstract of the Disclosure Cyproheptadine derivatives substituted with a trifluoromethylthio or trifluoromethylsulfonyl group in one of the benzo rings and having a hydroxyalkyl or cycloalkyl- alkyl group on the piperidine nitrogen are potent anti- psychotic agents, with a low propensity to induce extra- pyramidal side effects that are experienced with most major tranquilizers. The tranquilizing activity is pre- dominantly in the levorotatory enantiomers, whereas the dextrorotatory enantiomers have anticholinergic activity. Each enantiomer is useful as a source of the other by racemization. The novel compounds are prepared by treat- ment of the corresponding iodo or bromo compound with bis- (trifluoromethylthio) mercury and copper powder.
