摘要

Laevo- and dextrorotatory enantiomers correspond to the formula I or a salt thereof. R denotes hydrogen, fluorine or lower alkyl. They can be prepared by dehydration of a compound of the formula II. The laevorotatory enantiomer acts as an antipsychotic agent. The dextrorotatory enantiomer can be converted into the laevorotatory compound.
