Claim One:
1. A method for treating impairments of perception, concentration, learning and/or memory in a patient suffering from Alzheimer's disease or schizophrenia, comprising administering to the patient a compound represented by Formula (I): in an amount effective to stimulate an alpha7 nicotinic acetylcholine receptor (α7 nAChR), in which R 1 is a group of the formula —NR 2 —CO—NR 3 R 4 , —NR 2 —CO—CO—OR 5 , —NH—SO 2 R 6 , —SO 2 NHR 7 or —NH—CO—R 8 , where R 2 is hydrogen or C 1 -C 6 -alkyl, R 3 and R 4 are independently of one another hydrogen, C 1 -C 6 -alkyl, C 3 -C 8 -cycloalkyl or phenyl, which is optionally substituted by up to 3 radicals independently of one another selected from the group of halogen, cyano, C 1 -C 6 -alkyl, C 1 -C 6 -alkoxy, trifluoromethyl and trifluoromethoxy, or R 3 and R 4 together with the nitrogen atom to which they are bonded form a 5- to 6-membered heterocyclyl, R 5 is hydrogen, C 1 -C 6 -alkyl, C 3 -C 8 -cycloalkyl or aryl, where C 1 -C 6 -alkyl is optionally substituted by aryl, R 6 is C 1 -C 6 -alkyl, C 3 -C 8 -cycloalkyl, 5- to 6-membered heterocyclyl, aryl or 5- to 6-membered heteroaryl, where C 1 -C 6 -alkyl is optionally substituted by aryl, R 7 is hydrogen, C 1 -C 6 -alkyl, C 3 -C 8 -cycloalkyl, 5- to 6-membered heterocyclyl, aryl or 5- to 6-membered heteroaryl, where C 1 -C 6 -alkyl is optionally substituted by aryl, R 8 is C 3 -C 8 -cycloalkyl, C 1 -C 6 -alkyl or phenyl, where C 1 -C 6 -alkyl is substituted by C 1 -C 6 -alkoxy and phenyl by 1 to 3 radicals independently of one another selected from the group of halogen, cyano, C 1 -C 6 -alkyl, C 1 -C 6 -alkoxy, trifluoromethyl and trifluoromethoxy, or a salt thereof.
