Abstract
There are prepared compounds of the formula ##STR1## where R.sub.1 is hydrogen or hydroxy, R.sub.2 is hydrogen or R.sub.1 and R.sub.2 together represent a second bond between the carbon atoms carrying R.sub.1 and R.sub.2, Alk is a C.sub.2 -C.sub.6 alkylene group, R.sub.3 is a C.sub.3 -C.sub.8 -cycloalkyl group, a C.sub.1 -C.sub.6 -alkyl group, a C.sub.1 -C.sub.6 -hydroxyalkyl group or a C.sub.2 -C.sub.6 -hydroxyalkoxy-C.sub.1 -C.sub.6 -alkyl group and the groups R.sub.4, R.sub.5, R.sub.6 and R.sub.7 are the same or different and are hydrogen, C.sub.1 -C.sub.6 -alkyl group or halogen atoms, their N-oxides, their quaternary salts and their acid addition salts. There are also described processes for their production. The compounds have a strong bronchospasmolytic activity, antianaphylactic activity and an antihistamine-antiserotonine activity.
