実験手順
A mixture of 14 g. (36.3 mmoles) of diethyl 2-nitro-4-benzoylphenylmalonate, 300 ml. of 4N hydrochloric acid and 300 ml. of dioxane was heated to reflux for 10 hours. The reaction mixture was concentrated in vacuo and the crude product was triturated with hot methylene chloride, 9.88 g. (95% yield), m.p. 168°-170° C.
