Summary In the pure state 2-methyl-4-benzal-oxazolone-5 and 2-benzyl-4-benzal-oxazolone-5 are both colourless. The yellow 2-methyl-azlactone prepared by azlactone synthesis is contaminated with 2-styryl-4-benzal-oxazolone-5 which has obviously been formed from the 2-methyl-azlactone with excess benzaldehyde in an additional condensation reaction.
