  • 2-Aminotetralin derivatives and process for producing the same
    Patent number: 4239903
    Abstract: Compounds, which have antispasmodic effects, represented by the following formula (I) ##STR1## wherein R.sup.1 and R.sup.2, which may be the same or different, each represents a hydrogen atom, an alkoxy group or, when taken together, R.sup.1 and R.sup.2 represent an alkylenedioxy group; R.sup.3 represents a hydrogen atom, an alkyl group or a cycloalkyl group; R.sup.4, R.sup.5 and R.sup.6, which may be the same or different, each represents a hydrogen atom, an alkoxy group, an alkyl group, a halogen atom, a hydroxyl group or, when two of R.sup.4, R.sup.5 and R.sup.6 are taken together, they represent an alkylenedioxy group; and A represents a straight or branched chain alkylene group having 2 to 10 carbon atoms or an alkylene group having 2 to 10 carbon atoms and interrupted with an oxygen atom forming an ether bond therein, and the therapeutically useful acid-addition salts thereof; and a process for producing the same.
