The present invention relates to 4-, 5-, 6- or 7-methylene substituted indolyl derivatives of Formula 1, wherein R is aryl or heteroaryl, where said aryl or heteroaryl groups may be substituted one or more times with a substituent selected from hydrogen, halogen, cyano, nitro, C1-6-alkyl, C2-6-alkenyl, C2-6-alkynyl, C3-8-cycloalkyl, C3-8-cycloalkyl-C1-6-alkyl, C1-6-alkoxyl, C1-6-alkylthio, hydroxy, hydroxy-C1-6-alkyl, trifluoromethyl, trifluoromethylsulfonyl, C1-6-alkylsulfonyl, amino, C1-6-alkylamino, di-(C1-6-alkyl)amino, acyl, aminocarbonyl and a methylene dioxy group; X is N, C or CH; provided that the dotted line indicates a bond when X is C and no bond when X is N or CH; R<1> is hydrogen, C1-6-alkyl, C2-6-alkenyl, C2-6-alkynyl, C3-8-cycloalkyl, C3-8-cycloalkyl-C1-6-alkyl, aryl, aryl-C1-6-alkyl, acyl, thioacyl, C1-6-alkylsulfonyl, trifluoromethylsulfonyl or arylsulfonyl; and R<2> and R<3> are independently selected from hydrogen, halogen, cyano, nitro, C1-6-alkyl, C2-6-alkenyl, C2-6-alkynyl, C3-8-cycloalkyl, C3-8-cycloalkyl-C1-6-alkyl, C1-6-alkoxy, C1-6-alkylthio, hydroxy, hydroxy-C1-6-alkyl, trifluoromethyl, trifluoromethylsulfonyl, C1-6-alkylsulfonyl, amino, C1-6-alkylamino, di-(C1-6-alkyl)amino, acyl and aminocarbonyl. The compounds of the invention are selective dopamine D4 ligands.
