title: Pyrimidobenzodiazepines. Synthesis of pirenzepine analog.
abstract: The synthesis of Pyrimido[4,5-b][1,5]benzodiazepine derivatives from 4-(o-aminophenylene)amino-5-ethoxy-carbonyl-1,2-dihydro-6-methyl-2 - oxopyrimidine has been described. Pyrimidobenzodiazepine 5 alkylated with N-methyl-N'-chloroacetyl-piperazine gives a product related to pirenzepine. Compound 5 shows weak antianxiety and antidepressive action.
