A solventless synthesis of 2,4,10a-triaryl-1,10a-dihydro-2H-pyrazino[2,1-6] [1,3] benzoxazole has been achieved in good yield by the reaction of 2-[(2-oxo-2-arylethyl) anilino]-1-aryl-1-ethanones with 2-aminophenol in p-toluenesulfonic acid. The products have been characterized by 1H and 13C NMR spectroscopy.
