Ammonium metavanadate was found to be a practical catalyst for synthesizing 2-substituted aryl benzoxazoles, starting from 2-amino phenol and aromatic aldehydes in ethanol at room temperature. The method was proved to be simple and convenient, and the product was isolated with excellent yields.

Key words: ammonium metavanadate, 2-amino phenol, aromatic aldehyde, 2-substituted aryl benzoxazole
