Novel compounds useful as antihistamine agents, antiallergy agents, and bronchodilators are represented by the following formula ##SPC1## Wherein R represents hydrogen or hydroxy; R.sup.1 represents hydrogen; or R and R.sup.1 taken together form a second bond between the carbon atoms bearing R and R.sup.1 ; n is a positive whole integer of from 1 to 3; Z represents thienyl, phenyl, or substituted phenyl wherein the substituents on the substituted phenyl may be attached at the ortho, meta, or para positions of the phenyl ring and are selected from halogen, a straight or branched lower alkyl chain of from 1 to 4 carbon atoms, a lower alkoxy group of from 1 to 4 carbon atoms, di(lower)alkylamino, or a saturated monocyclic heterocyclic group such as pyrrolidino, piperidino, morpholino, or N-(lower)alkylpiperazino. Pharmaceutically acceptable acid addition salts and individual optical isomers of compounds of the above formula are also included as a part of this invention.
