Claims
- 1. A method for modifying the growth of useful livestock comprising administering to such livestock an amount effective therefor of a monosilylated aminophenylethylamine derivative of the formula ##STR24## in which X and Y are identical or different and represent hydrogen or CN,
- R.sup.2 represents hydrogen or methyl,
- R.sup.3 represents t-butyl, isopropyl, monofluoro-t-butyl or 1-cyclohexyl-ethyl, and
- R.sup.4, R.sup.5 and R.sup.6 denote a straight-chain or branched alkyl radical,
- or a physiologically tolerated salt thereof.
- 2. The method according to claim 1, in which R.sup.3 represents monofluoro-t-butyl or 1-cyclohexyl-ethyl.
- 3. The method according to claim 1, wherein such compound is 1-(4-amino-3,5-dichlorophenyl)-0-(1,2-dimethylpropyl-di-methylsilyl)-2-(2-fluoro-1,1-dimethyl-ethylamino) ethanol of the formula ##STR25## or a physiologically tolerated salt thereof.
- 4. The method according to claim 1, wherein such compound is 1-(4-amino-3,5-dichlorophenyl)-0-(dimethylhexylsilyl)-2-[R]-1-cyclohexyl-ethylamino)-ethanol of the formula ##STR26## or a physiologically tolerated salt thereof.
- 5. A growth-modifying composition comprising an edible food base and a livestock-promoting effective amount of a monsilylated aminophenylethylamine derivative of the formula ##STR27## in which X and Y are identical or different and represent hydrogen or CN,
- R.sup.2 represents hydrogen or methyl,
- R.sup.3 represents t-butyl, isopropyl, monofluoro-t-butyl or 1 -cyclohexyl-ethyl, and
- R.sup.4, R.sup.5 and R.sup.6 denote a straight-chain or branched alkyl radical,
- or a physiologically tolerated salt thereof.
- 6. A compound of the formula ##STR28## in which X and Y are identical or different and represent hydrogen, halogen or CN,
- R.sup.4, R.sup.5 and R.sup.6 denote a straight-chain or branched alkyl radical,
- R.sup.2 represents hydrogen or methyl,
- R.sup.3 represents monofluoro-t-butyl or 1-cyclohexyl-ethyl,
- or a physiologically tolerated salt thereof.
- 7. A compound according to claim 6, wherein such compound is 1-(4-amino-3,5-dichlorophenyl)-0-(1,2-dimethylpropyl-di-methylsilyl)-2-(2-fluoro-1,1-dimethyl-ethyalmino) ethanol of the formula ##STR29## or a physiologically tolerated salt thereof.
- 8. A compound according to claim 6, wherein such compound is i-(4-amino-3,5-dichlorophenyl)-0-(dimethylhexylsilyl)-2-1-cyclohexyl-ethylamino)-ethanol of the formula ##STR30## or a physiologically tolerated salt thereof.
- 9. A livestock-growth-modifying composition comprising an amount effective therefor of a compound or salt according to claim 6.
- 10. A compound of the formula ##STR31## in which X and Y, independently of one another, represent hydrogen, halogen or CN,
- R.sup.2 represents hydrogen or methyl,
- R.sup.3 represents 1-cyclohexyl-ethyl.
- 11. 1-(4-Amino-3,5-dichloro-phenyl)-2-(1-cyclohexyl-ethyl-amino)-ethanol of the formula ##STR32## or a physiologically tolerated salt thereof.
- 12. A growth-modifying composition comprising an edible food base and a growth-modifying effective amount of a compound or salt according to claim 11.
- 13. A method for modifying the growth of useful livestock comprising administering to such livestock an amount effective therefor of a compound or salt according to claim 11.
