The present invention relates to compounds of general formula
wherein
R
1
is aryl or heteroaryl, which are optionally substituted by one, two or three substituents, selected from lower alkyl, halogen, lower alkyl substituted by halogen, hydroxyl, lower alkoxy, lower alkoxy substituted by halogen, cyano or nitro;
R
2
is halogen, lower alkyl or cyano;
R
3
is hydrogen or lower alkyl;
R
4
is hydrogen or lower alkyl;
R
5
, R
6
are hydrogen, lower alkyl, or may form together with the N-atom to which they are attached a heterocycloalkyl ring;
or to a pharmaceutically acceptable acid addition salt, to a racemic mixture or to its corresponding enantiomer and/or optical isomers thereof.
The compounds may be used for the treatment of schizophrenia, obsessive-compulsive personality disorder, major depression, bipolar disorders, anxiety disorders, normal aging, epilepsy, retinal degeneration, traumatic brain injury, spinal cord injury, post-traumatic stress disorder, panic disorder, Parkinson's disease, dementia, Alzheimer's disease, cognitive impairment, chemotherapy-induced cognitive dysfunction (“chemobrain”), Down syndrome, autism spectrum disorders, hearing loss, tinnitus, spinocerebellar ataxia, amyotrophic lateral sclerosis, multiple sclerosis, Huntington's disease, stroke, and disturbances due to radiation therapy, chronic stress, or abuse of neuro-active drugs, selected from alcohol, opiates, methamphetamine, phencyclidine and cocaine.
