Potassium Carbonate → 3-(4-Nitrophenyl)pentane-2,4-dione

참여 물질

반응 단계

A mixture of pentane-2,4-dione (4.41 g, 40 mmol), 1-iodo-4-nitrobenzene (5 g, 20 mmol) and potassium carbonate (11 g, 80 mmol) were heated in DMSO (15 ml) at 120° C. for 3 hr. The reaction mixture was cooled to room temperature, diluted with water (100 ml), and then extracted with ethyl acetate. The organic layer was washed with water, brine and dried. Evaporation gave a residue which was chromatographed over silica gel eluting with ethyl acetate/pet ether (5:95) to give 3-(4-nitrophenyl)-pentane-2,4-dione (2.67 g, 60%) as solid.
