摘要:
Derivatives of 2,3-benzodiazepine are substituted by one or two halogen atom(s) and have the general formula ##STR1## These derivatives are non-competitive AMPA antagonists and are used in pharmaceutical compositions. A process to make the 2,3-benzodiazepine derivatives includes converting starting compounds which are substituted by one or two halogen groups and have the general formula ##STR2##
