New compounds of the formula ##STR1## are disclosed wherein R.sub.1 =H, linear or branched alkyl-radical with from 1 to 6 carbon atoms, cycloalkyl radical with from 3 to 6 carbon atoms, alkylphenyl radical where the phenyl group may be in turn substituted with a hydroxy or methoxy group; R.sub.2 =hydroxy, hydromethyl R.sub.3 =H, alkyl with 1-4 carbon atoms, formyl, carboalkyl where the alkyl groups have 1-3 carbon atoms, carbomido group simple or mono- or di-substituted on the nitrogen atom with alkyl radicals containing 1-3 carbon atoms. The new compounds are useful in the treatment of bronchial affections. They are endowed with unique properties in that they provide the desired bronchial dilation effect without any concomitant cardiac stimulation.
