1. A compound of formula (I) in which A represents a group of the formula where# is the point of attachment to the piperidine ring,* is the point of attachment to R2,R4 represents hydrogen or C1-C3-alkyl,andR5 represents hydrogen or C1-C3-alkyl, R1 represents phenyl,
where phenyl may be substituted by 1 to 3 substituents independently of one another selected from the group consisting of monofluoromethyl, difluoromethyl, trifluoromethyl, monofluoromethoxy, difluoromethoxy, trifluoromethoxy, monofluoromethylsulphanyl, difluoromethylsulphanyl, trifluoromethylsulphanyl, methylsulphonyl, C1-C4-alkyl, C1-C4-alkoxy and C1-C4-alkoxycarbonyl, R2 represents phenyl
where phenyl may be substituted by 1 to 3 substituents independently of one another selected from the group consisting of halogen, cyano, hydroxyl, amino, monofluoromethyl, difluoromethyl, trifluoromethyl, monofluoromethoxy, difluoromethoxy, trifluoromethoxy, monofluoromethylsulphanyl, difluoromethylsulphanyl, trifluoromethylsulphanyl, C1-C4-alkyl, C1-C4-alkoxy, C1-C6-alkylamino and phenyl,
where phenyl may be substituted by 1 to 3 substituents independently of one another selected from the group consisting of halogen and trifluoromethyl, R3 represents 4- to 7-membered heterocyclyl,
where heterocyclyl, may be substituted by 1 to 3 substituents independently of one another selected from the group consisting of halogen, cyano, oxo, hydroxyl, amino, monofluoromethyl, difluoromethyl, trifluoromethyl, monofluoromethoxy, difluoromethoxy, trifluoromethoxy, monofluoromethylsulphanyl, difluoromethylsulphanyl, trifluoromethylsulphanyl, hydroxycarbonyl, aminocarbonyl, C1-C4-alkyl, C1-C4-alkoxy, C1-C6-alkylamino, C1-C4-alkoxycarbonyl, C1-C4-alkylaminocarbonyl and cyclopropyl,
