  The invention relates to novel substituted pyrazolopyrimidines. Chemically, the compounds are characterised by general Formula (I): with R 1 being phenyl or pyridyl, any of which is substituted with 1 to 4, preferably 1 to 3 substituents X; X independently of each other being selected from C 2 -C 6 -alky 1 or Ci-C 6 -alkoxy, where C 2 -C 6 -alkyl and C 1 -C 6 -alkoxy are at least dihalogenated up to perhalogenated. preferably with 2 to 6 halogen substituents, and the halogen atoms being selected from the group of fluoro, chloro and bromo, preferably fluoro; R 2 being phenyl or heteroaryl, where phenyl is substituted by 1 to 3 radicals and heteroaryl is optionally substituted by 1 to 3 radicals in each case independently of one another selected from the group of C 1 -C 6 -alkyI, C 1 -C 6 -alkoxy, hydroxycarbonyl, cyano, trifluoromethyl, amino, nitro, hydroxy, C 1 -C 6 -alkylamino, halogen, C 6 -C 10 -arylcarbonylamino, C 1 -C 6 -alkylcarbonylamino, C 1 -C 6 -alkylaminocarbonyl. C 1 -C 6 -alkoxycarbonyl, C 6 -C 10 -arylaminocarbonyl, heteroarylaminocarbonyl. heteroarylcarbonylamino, C 1 -C 6 -alkylsulphonyl-amino, C 1 -C 6 -alkylsulphonyl and C 1 -C 6 -alkylthio; The new compounds shall be used for the manufacture of medicaments, in particular medicaments for improving, perception, concentration, learning and/or memory in patients in need thereof.
