A few 2-aryl and heterocyclic (6,7) coumarinoxazoles have been synthesised by condensing 6-amino-7-hydroxy-3-phenyl-4-methylcuomarin with aromatic and heterocyclic carboxylic acids with the aid of polyphosphoric acid.The ultraviolet, infrared, nmr, mass and fluorescence spectra of these compounds have been presented for characterisation.
