A simple, rapid and efficient procedure for the synthesis of 2 -arylbenzoxazole derivatives has been developed from 2-aminophenol and arylaldehydes by using 1, 3-dibromo-5, 5-dimethylhydantoin (DBH) in moderate to good yields under solvent-free microwave irradiation. The remarkable efficiency of DBH under solvent free microwave irradiation leads to many advantages like, the use of non-corrosive and inexpensive reagents, simple workup procedure and good yields in addition to the eco-friendly "green chemistry" economical and environmental impacts.
