Abstract: Treatment of unsaturated azlactones with p-nitrophenylhydrazine in boiling xylene gives the corresponding  α,ß-disubstituted acrylic acid p-nitrophenylhydrazides. Boiling in acetic acid of some unsaturated azlactones with phenylhydrazine or я-nitrophenylhydrazine gave in one step N-anilino- or N-(p-nitroanilino)-2,4-disubstituted 2-imidazoline-5-ones.
