A series of novel N-alkyl or oxyalkyl arylpiperidine derivatives have been prepared, including their pharmaceutically acceptable acid addition salts, wherein the N-alkyl or oxyalkyl side chain is further substituted by certain aryl or heterocyclic ring groups. These particular compounds are useful in therapy as neuroleptic agents for the control of various psychotic disorders. Typical and preferred member compounds include 4-4-4-(2-methoxyphenyl)-1-piperidinyl]ethyl}phenyl}}thiazole-2-amine, 4-4-4-[4-(2-methoxyphenyl)-1-piperidinyl]-n-butyl}phenyl}}thiazole-2-amine, 3-4-[4-(2-methoxyphenyl)-1-piperidinyl]-n-butyl}-1,8,8-trimethyl-3-azabicyclo[3.2.1]heptane-2,4-dione, 5-2-[4-(2-methoxyphenyl)-1-piperidinyl]ethyl}oxindole and 3-2-[4-(1-naphthyl)-1-piperidinyl]ethyl}2-methyl-4H-pyrido[1,2-a]pyrimidine-4-one, respectively. Methods for preparing all these compounds from known starting materials are provided.
现已制备出一系列新型 N-烷基或氧烷基芳基哌啶衍生物,包括其药学上可接受的酸加成盐,其中 N-烷基或氧烷基侧链进一步被某些芳基或杂环基团取代。这些特殊化合物可作为神经安定剂用于治疗,控制各种精神障碍。典型和优选的成员化合物包括 4-4-4-(2-甲氧基苯基)-1-哌啶基]乙基}苯基}噻唑-2-胺、4-4-4-[4-(2-甲氧基苯基)-1-哌啶基]-正丁基}苯基}噻唑-2-胺、3-4-[4-(2-甲氧基苯基)-1-哌啶基]-正丁基}-1,8,8-三甲基-3-氮杂双环[3.2.1]庚烷-2,4-二酮、5-2-[4-(2-甲氧基苯基)-1-哌啶基]乙基}氧化吲哚和 3-2-[4-(1-萘基)-1-哌啶基]乙基}2-甲基-4H-吡啶并[1,2-a]嘧啶-4-酮。本文提供了用已知起始原料制备所有这些化合物的方法。
