Monosilylated aminophenylethyl amine derivatives, process for their preparation and their use for promoting growth

摘要

The present invention relates to monosilylated aminophenylethylamine derivatives of the general formula (I) in the X and Y are identical or different and represent hydrogen or halogen, R ₂ is hydrogen or a straight-chain, branched, means saturated or unsaturated alkyl radical having up to 10 carbon atoms, R ₃ is hydrogen or a straight-chain, branched, saturated or unsaturated alkyl radical, preferably chlorine, fluorine may be substituted by halogen and / or a phenyl radical which is optionally substituted by halogen, hydroxy, alkyl. Aryl, alkoxy, alkylthio, optionally substituted phenoxy or phenylthio, cyano or trifluoromethyl may be substituted, a heterocyclic radical or together with R ₂ is a nitrogen-containing saturated heterocyclic group such as azabicyclononane, substituted azabicyclononane, azabicyclooctane and the like and R _4, R _5, R ₆ represent a straight-chain or branched alkyl radical, and their physiologically acceptable salts found.; The substances have excellent growth-promoting effects and also result in an improvement of the meat-fat ratio in favor of meat.; The invention also relates to a method of preparing these compounds.
