Patent ID: 8546438

Claim:
A compound of formula in which R 1 represents phenyl, whereby phenyl is substituted with 1 to 3 substituents, whereby the substituents are selected independently of one another from the group consisting of halogen, hydroxy, cyano, nitro, trifluoromethyl, trifluoromethoxy, trifluoromethylthio, (C 1 -C 4 )-alkyl and (C 1 -C 4 )-alkoxy, wherein (C 1 -C 4 )-alkyl and (C 1 -C 4 )-alkoxy in turn may be substituted one to three times identically or differently with radicals selected from the group consisting of halogen, cyano, hydroxy, (C 1 -C 4 )-alkoxy, amino, mono-(C 1 -C 4 )-alkylamino, di-(C 1 -C 4 )-alkylamino, (C 3 -C 7 )-cycloalkyl and 4-to 7-membered heterocyclyl, whereby the last-mentioned cycloalkyl and heterocyclyl radicals in turn may each be substituted up to three times identically or differently with substituents selected from the group consisting of halogen, cyano, (C 1 -C 4 )-alkyl, trifluoromethyl, hydroxy, (C 1 -C 4 )-alkoxy, trifluoromethoxy, oxo, amino, mono-(C 1 -C 4 )-alkylamino and di-(C 1 -C 4 )-alkylamino, and R 2 represents phenyl, whereby phenyl is substituted with 1 to 3 substituents, whereby the substituents are selected independently of one another from the group consisting of halogen, hydroxy, cyano, nitro, trifluoromethyl, trifluoromethoxy, trifluoromethylthio, (C 1 -C 4 )-alkyl and (C 1 -C 4 )-alkoxy, wherein (C 1 -C 4 )-alkyl and (C 1 -C 4 )-alkoxy in turn may be substituted one to three times identically or differently with radicals selected from the group consisting of halogen, cyano, hydroxy, (C 1 -C 4 )-alkoxy, amino, mono-(C 1 -C 4 )-alkylamino, di-(C 1 -C 4 )-alkylamino, (C 3 -C 7 )-cycloalkyl and 4-to 7-membered heterocyclyl, whereby the last-mentioned cycloalkyl and heterocyclyl radicals in turn may each be substituted up to three times identically or differently with substituents selected from the group consisting of halogen, cyano, (C 1 -C 4 )-alkyl, trifluoromethyl, hydroxy, (C 1 -C 4 )-alkoxy, trifluoromethoxy, oxo, amino, mono-(C 1 -C 4 )-alkylamino and di-(C 1 -C 4 )-alkylamino, or one of the salts thereof.
