A process is described wherein pyrido[1,4]benzodiazepines having the formula:
wherein Q is NR¹R² or
are prepared from unsubstituted pyridobenzodiazepinones by alkylation reaction with halo-alkyl-Q followed by acylation of the other nitrogen; breaking the ring with an aryl Grignard reagent and recyclizing to add the aryl radical and form the azepine ring. Novel intermediates are thereby disclosed.
描述了一种工艺,其中吡啶并[1,4]苯并二氮杂卓具有以下式子:
其中 Q 为 NR¹R² 或
由未取代的吡啶并二氮杂卓通过以下方法制备:与卤代烷基-Q 进行烷基化反应,然后对另一个氮进行酰化;用芳基格氏试剂破环,然后再反应以加入芳基并形成氮杂卓环。由此揭示了新型中间体。
