    摘要: The invention relates to novel substituted pyrazolopyrimidines. Chemically, the compounds are characterized by general Formula (I): with R1 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 C2-C6-alky1 or Ci-C6-alkoxy, where C2-C6-alkyl and C1-C6-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; R2 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 C1-C6-alkyl, C1-C6-alkoxy, hydroxycarbonyl, cyano, trifluoromethyl, amino, nitro, hydroxy, C1-C6-alkylamino, halogen, C6-C10-arylcarbonylamino, C1-C6-alkylcarbonylamino, C1-C6-alkylaminocarbonyl. C1-C6-alkoxycarbonyl, C6-C10-arylaminocarbonyl, heteroarylaminocarbonyl. heteroarylcarbonylamino, C1-C6-alkylsulphonyl-amino, C1-C6-alkylsulphonyl and C1-C6-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.
