Abstract

Abstract The invention provides compounds of general formula I ##STR1## and pharmaceutically acceptable acid addition and quaternary ammonium salts thereof, wherein R represents hydrogen or lower alkyl, R 1 represents hydrogen or lower alkyl, R 2 represents hydrogen or lower alkyl, R 3 represents hydrogen, halogen, lower alkoxy, hydroxy, or lower alkyl, R 4 represents hydrogen, lower alkyl, cycloalkyl of 5 to 7 carbon atoms, thienyl, furyl, phenyl; phenyl mono- or disubstituted by halogen, lower alkyl, lower alkoxy, hydroxy or trifluoromethyl; or benzoyl, halobenzoyl, lower alkanoyl, cycloalkanoyl of 6 to 8 carbon atoms, or thienoyl, A represents an alkylene, mono- or diketo- or hydroxy-alkylene radical having from 1 to 5 carbon atoms and X is oxygen or sulphur. The compounds exhibit action on the cardiovascular system particularly hypotensive and/or anti-hypertensive activity.
