실험 절차

22g of finely powdered 3-benzoylacrylic acid was added in 1-gram portions to 11 g of stirred fuming (90%) nitric acid at -5° over a 30 minute period, the mixture being allowed to heat to 0°. Then the temperature of the mixture was allowed to rise to 2° and held until a clear solution was obtained. The mixture then was poured on ice, and the solid which formed was filtered, washed with water, dried (MgSO4) and recrystallized from ethanol to give 3-(3-nitrobenzoyl)acrylic acid (8A), m.p.: 199°-201°.
