Alumina-supported phosphorus pentoxide was found to be an efficient reagent for the synthesis of 1, 5-benzodiazepine derivatives from phenylenediamine and ketones in the solvent-free condition under microwave irradiation. This method is an easy, rapid, and high-yielding reaction for the synthesis of 1, 5-bezodiazepines.
