Compounds of formula (I) wherein R1, R2, R3, R4, R5, X and Y have the meanings defined below, process of manufacturing these compounds and pharmaceuticals containing such a compound have HDAC inhibitor activity. R1 is selected from hydrogen, (1-4C)alkyl, COOH, COO(1-4C)alkyl, R2, R3, R4, R5 are independently selected from hydrogen, a halogen atom, an (1-4C)alkyl-, trifluoromethyl-, hydroxy-, (1-4C)alkoxy-, aryloxy-, arylalkyloxy-, nitro-, amino-, (1- 4C)alkylamino-, di[1-4C)alkyl]-amino, piperidino, morpholino, pyrrolidino, (1- 4C)alkanoylamino-, or an aryl group, or a heteroaryl group, or R2 and R3 together or R3 and R4 together or R4 and R5 together, respectively, can form an (1-3C)alkylenedioxy ring, or R2 and R3 together or R3 and R4 together or R4 and R5 together, respectively, can form an (3-5C)alkylene chain. Y is CH2-CH2- . X is an alkylene-chain of 4 to 10 carbon atoms which can be saturated or unsaturated with one or two double bonds or one or two triple bonds or a one double and one triple bond, and which can be branched or unbranched or interrupted by a (3-7C) cycloalkylring.
