技术领域
本发明涉及一种制备式
I的3-{2-[4-(6-氟苯并[d]异唑-3-基)-哌啶-1-基]-乙基}-2-甲基-6,7,8,9-四氢-4H-吡啶并-[1,2-a]嘧啶-4-酮的方法。
被称为利培酮的式
I的化合物就其抗精神病性而言是一种药学活性的化合物。
本发明的另一个实施方案是式
II的化合物,(2-甲基-4-氧代-6,7,8,9-四氢-4H-吡啶并[1,2-a]嘧啶-3-基)-乙醛,和式
III的化合物,3-{2-[4-(6-氟苯并[d]异唑-3-基)-哌啶-1-基]-乙烯基}-2-甲基-6,7,8,9-四氢-吡啶并[1,2-a]嘧啶-4-酮。这些化合物在式
I化合物制备过程中是合成中间体。
以前一直没有对化合物
II和
III进行过描述。
背景技术
EP0196132公开了制备3-{2-[4-(6-氟苯并[d]异唑-3-基)-哌啶-1-基]-乙基}-2-甲基-6,7,8,9-四氢-4H-吡啶并-[1,2-a]嘧啶-4-酮(I)的不同方法,其包括通过不同官能团间进行的分子间缩合所进行的不同中间体的环化,其给出了2-甲基-6,7,8,9-四氢-4H-吡啶并-[1,2-a]嘧啶-4-酮系统。这些过程中的大多数通常保留了使用十分复杂的中间体并在最后的合成步骤中使用必然影响最后过程的总费用的成问题的反应。
在EP0196132中,还可以通过另一种方法来制备3-{2-[4-(6-氟苯并[d]异唑-3-基)-哌啶-1-基]-乙基}-2-甲基-6,7,8,9-四氢-4H-吡啶并-[1,2-a]嘧啶-4-酮(
I),该方法包括通过6-氟-3-(4-哌啶基)-苯并[d]异唑(IV)与3-(2-氯乙基)-2-甲基-6,7,8,9-四氢-4H-吡啶并[1,2-a]嘧啶-4-酮或带有其它离去基团的类似衍生物(
V)的分子间N-烷基化反应形成C-N键(流程图1)。
