Process for the preparation of aryl-pyrido(1,4) benzodiazepines |
| abstract |
A process is described wherein pyrido[1,4]benzodiazepines having the formula: ##STR1## wherein Q is NR 1 R 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. |
