The present invention relates to compounds of formula wherein R1 is C4-6-cycloalkyl or C4-6-heterocycloalkyl, which are optionally substituted by one or two substituents, selected from hydroxy or lower alkyl; A is phenyl, pyridinyl or piperidinyl; R2 is hydrogen, halogen, lower alkyl, cyano, C4-6-cycloalkyl, lower alkoxy, lower alkoxy substituted by halogen, or is a five-or six-membered heteroaryl, optionally substituted by lower alkyl; n is 1 or 2; 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 or prophylaxis of Alzheimer's disease, cognitive impairment, schizophrenia, pain or sleep disorders.
本发明涉及通式化合物,其中R1为C4-6环烷基或C4-6杂环烷基,其可任选地被一个或两个选自羟基或低级烷基的取代基取代;A为苯基、吡啶基或哌啶基;R2为氢、卤素、低级烷基、氰基、C4-6环烷基、低级烷氧基、被卤素取代的低级烷氧基,或为可任选地被低级烷基取代的五元或六元杂芳基;n为1或2;或涉及药学上可接受的酸加成盐、外消旋混合物或其相应的对映体和/或光学异构体。这些化合物可用于治疗或预防阿尔茨海默病、认知障碍、精神分裂症、疼痛或睡眠障碍。
