NEW BETAMIMETICS HAVING A LONG-LASTING ACTIVITY, PROCESSES FOR PREPARINGTHEM AND THEIR USE AS MEDICAMENTS

摘要

The invention relates to betamimetics of the general formula (1), wherein R1represents a group (a), where R3 represents benzyl which can optionally besubstituted by methoxy, R4 represents hydrogen, or R3 and R4 conjointlyrepresent a -CO-CH2-O- bridge, whereby the carbonyl group of this bridge isbonded to the nitrogen; R2 represents a group selected from (b) and (c),whereby R5 represents dimethylamino, methoxy or butoxy, X represents anitrogen or a carbon, R6 represents methoxyphenyl if X is nitrogen, or if X iscarbon, an annellated phenyl ring likewise linked to X. The invention alsorelates to a method for the production of said betamimetics and to their useas medicaments.
