The present invention relates to compounds of the general formula (I) wherein R1 is lower alkyl, -(CH2)n-aryl, unsubstituted or substituted by one or two substituents, selected from the group consisting of lower alkyl, lower alkoxy, -OCF3, halogen, -NR’R” or trifluoromethyl, or heteroaryl; R2 is lower alkyl, -(CH2)n-aryl, unsubstituted or substituted by one or two substituents, selected from the group consisting of lower alkyl, lower alkoxy, halogen, trifluoromethyl, nitro, cyano, -NR’R”, hydroxy, or by a heteroaryl group, or is heteroaryl, unsubstituted or substituted by one or two substituents, selected from the group consisting of lower alkyl or halogen; R3 is heteroaryl or is aryl, unsubstituted or substituted by halogen or lower alkyl; R4 is hydrogen or hydroxy; A is -S(O)2-or-C(O)-; X,Y are independently from each other -CH2- or -O-, with the proviso that X and Y are not simultaneously -O; R’R” are independently from each other hydrogen, lower alkyl or -C(O)-lower alkyl; n is 0, 1 or 2; and to pharmaceutically acceptable acid addition salts thereof. The compounds may be used for the treatment of psychoses, pain, disfunction in memory and learning, schizophrenia, dementia and other diseases in which cognitive processes are impaired, such as attention deficit disorders or Alzheimer’s disease.
本发明涉及一般式(I)的化合物,其中R1为较低的烷基,-(CH2)n-芳基,未取代或被选自较低烷基、较低烷氧基、-OCF3、卤素、-NR’R”或三氟甲基的一种或两种取代基所取代,或杂芳基;R2为较低的烷基,-(CH2)n-芳基,未取代或被选自较低烷基、较低烷氧基、卤素、三氟甲基、硝基、氰基、-NR’R”、羟基,或由杂芳基所取代的一种或两种取代基,或为杂芳基,未取代或被选自较低烷基或卤素的一种或两种取代基;R3为杂芳基或为芳基,未取代或被卤素或较低烷基所取代;R4为氢或羟基;A为-S(O)2-或-C(O)-;X,Y分别为-CH2-或-O-,但X和Y不能同时为-O;R’R”分别为氢、较低烷基或-C(O)-较低烷基;n为0、1或2;以及其药学上可接受的酸盐。这些化合物可用于治疗精神病、疼痛、记忆和学习功能障碍、精神分裂症、痴呆症和其他认知过程受损的疾病,如注意力缺陷障碍或阿尔茨海默病。
