Abstract
An efficient procedure for the one-pot chemoselective synthesis of 2H-benzo [b][1, 4] oxazin- 3 (4H)-one derivatives from their corresponding o-aminophenols is developed using DBU in the ionic liquid [omim][BF4]. Upon completion of the reaction and separation of the product, the ionic liquid is recovered and successfully reused over nine recycles without any noticeable loss of performance.
