The invention relates to piperidine compounds of formula (I):
wherein X—R1 represents —N(H)-pyrimidinyl, wherein said pyrimidinyl is unsubstituted or mono-substituted wherein the substituent is selected from (C1-4)alkyl or halogen, or X—R1 represents —NH—C(O)-heterocyclyl, wherein the heterocyclyl is selected from benzofuranyl and imidazo[2,1-b]-thiazolyl, wherein said heterocyclyl is unsubstituted or independently mono-, di- or tri-substituted wherein the substituents are independently selected from (C1-4)alkyl; A represents a phenyl- or thiazolyl-group, wherein the phenyl or thiazolyl is unsubstituted or mono-substituted with (C1-4)alkyl; B represents a phenyl-group, wherein the phenyl is unsubstituted or mono-, or di- substituted, wherein the substituents are independently selected from the group consisting of (C1-4)alkyl, (C1-4)alkoxy, trifluoromethyl, cyano and halogen; to pharmaceutically acceptable salts thereof, and to the use of such compounds use as medicaments, especially as orexin receptor antagonists.
本发明涉及式(I)的哌啶化合物:其中X - R1表示 -N(H)-嘧啶基,其中所述的嘧啶基未取代或单取代,所述取代基从(C1-4)烷基或卤素中选择;或X-R1表示-NH-C(O)-杂环基,所述杂环基从苯并呋喃基和咪唑[2,1-b]-噻唑基中选择,所述杂环基未取代或独立单取代,二取代或三取代,所述取代基独立选择自(C1-4)烷基;A表示苯基或噻唑基,其中苯基或噻唑基未取代或单取代,所述取代基独立选择自(C1-4)烷基;B表示苯基,其中苯基未取代或单取代或二取代,所述取代基独立选择自(C1-4)烷基,(C1-4)烷氧基,三氟甲基,氰基和卤素中的一种或多种;以及其制成的药学上可接受的盐,并将此类化合物用作药物,特别是用作促进睡眠的药物。
