摘要

The present invention concerns the compounds of formula the N-oxide forms, the pharmaceutically acceptable addition salts and the stereochemically isomeric forms thereof, wherein R<1> is hydrogen, optionally substituted C1-6alkyl, aryl; R<2> is each independently a halogen, hydroxy, C1-6alkyl, C1-6alkyloxy or nitro; n is 0,1,2 or 3: Alk is C1-6alkanediyl; D is an optionally substituted saturated or unsaturated nitrogen containing heterocycle; and aryl is optionally substituted phenyl; having an affinity for the serotonin receptors. It further relates to their use as a medicine, their preparation as well as compositions containing them.
