Abstract
1,5-Benzodiazepine derivatives were synthesized in moderate to excellent isolated yields by the condensation reactions of o-phenylenediamine and ketones catalyzed by [1-methyl-3-(3-sulphopropyl)imidazolium methyl sulphate] under ultrasound irradiation using n-hexane as solvent. This method is simple, effective and gives better yields.
