Compounds of formula I wherein, X is phenyl unsubstituted or optionally substituted with one or more cyano, halogeno, halogenoalkyl, C1-6-alkoxy, C1-6-alkyl, C1-5-alkanoyl, C3-5-alkenyl, aryloxy, aralkoxy, amino, C1-6-alkyl mono or disubstituted amino, C1-4-alkanoylamino, carbamoyl, C1-4-alkyl N-mono or disubstituted carbamoyl, C1-4-alkyl substituted with amino, C1-2-alkyl mono or disubstituted amino, N02, morpholino or imidazolyl; and, R is 3,4-methylenedioxyphenyl, aryl or heteroaryl all of which can be optionally substituted with one or more cyano, halogeno, C1-6-alkyl, C1-6-alkoxy, C2-6-alkenyl, trifluoromethyl, C3-5-alkylene, aryloxy, aralkoxy or C1-6-alkylthio; and, R1 and R2 are C1-10-alkyl, C3-7-cycloalkyl, C2-10-alkenyl, C3-6-cycloalkyl-C1-5-alkyl, all of which can be unsubstituted or substituted with C1-5-alkyl, C1-5-alkoxy or cyano; or, R1 and R2 together form a 5, 6 or 7 membered ring containing at least one nitrogen atom, or which optionally contains two nitrogen atoms, one or two oxygen atom(s) or one or two sulphur atom(s) or a combination thereof, which ring is unsubstituted or optionally substituted with C1-4-alkyl, C1-4-alkoxy or aryl; and, R3, R4, R5, R6, and R7 independently are hydrogen, C1-4-alkyl or phenyl; or, R4 and X together form a carbocyclic ring containing 5 or 6 atoms, or a salt thereof with a pharmaceutically acceptable acid; provided however that R1 and R2 are not C3-7-cycloalkyl, C1-10-alkyl or C2-10-alkenyl which may be straight, branched or cyclic, unsubstituted or substituted with C1-4-alkoxy, aryloxy or cycloalkyl, cyano or cycloalkylalkyl, when X is phenyl substituted with cyano, halogen, halogenalkyl, C1-6-alkoxy, C1-6-alkyl, C1-5-alkanoyl, C3-5-alkylene, aryloxy or aralkoxy, are useful in the treatment of anoxia, traumatic injury, ischemia, migraine, epilepsy, Parkinson's disease, Alzheimer's disease and other neurodegenerative diseases.
