摘要：
A simple and convenient method is reported for the synthesis of 2,3-dihydro-1H-1,5-benzodiazepine from o-phenylene-diamine and ketones in aqueous methanol using IL, tetraalkylammonium bromate, as the cyclodehydration catalyst. The synthetic protocol is simple and reaction accomplished at ambient temperature. Yields are good and work up easy.
