A process is described wherein pyrido[1,4]benzodiazepines having the formula: ##STR1## wherein Q is NR.sup.1 R.sup.2 or ##STR2## 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.
描述了一种过程,其中通过烷基化反应与卤代烷基-Q反应制备具有以下
化学式的
吡啶并[1,4]苯二氮杂
环己烯类化合物:其中Q是NR^1R^2或;然后通过对另一氮进行酰化反应;用芳基
