Claim:
An 1-[(indol-3-yl)carbonyl]piperazine derivative having the general formula I wherein R represents 1-4 substituents independently selected from H, (C 1-4 )alkyl (optionally substituted with halogen), (C 1-4 )alkyloxy (optionally substituted with halogen), halogen, OH, NH 2 , CN and NO 2 ; R 1 is (C 5-8 )cycloalkyl or (C 5-8 )cycloalkenyl; R 2 is H, methyl or ethyl; R 3 , R 3 ′, R 4 ′ R 4 ′, R 5 , R 5 ′ and R 6 ′ are independently hydrogen or (C 1-4 )alkyl, optionally substituted with (C 1-4 )alkyloxy, halogen or OH; R 6 is hydrogen or (C 1-4 )alkyl, optionally substituted with (C 1-4 )alkyloxy, halogen or OH; or R 6 forms together with R 7 a 4-7 membered saturated heterocyclic ring having only carbons as additional ring members; or R 7 is H, (C 1-4 )alkyl or (C 3-5 )cycloalkyl, the alkyl groups being optionally substituted with OH, halogen or (C 1-4 )alkyloxy; or a pharmaceutically acceptable salt thereof.
