Abstract

The first report of the use of an ionic liquid as a soluble support for the synthesis of 1,4-benzodiazepine-2,5-diones is reported in this paper. This synthetic method is simple and efficient and the products are obtained in good yields. All of the products were characterized by IR, ¹H NMR, and ¹³C NMR.
