実験手順
2-Bromo-4-nitrophenol (2.5 g; Desc. 9), 2-iodopropane (2.2 g) and potassium carbonate (5 g) were refluxed in acetone (30 ml) for 18 hours. The reaction mixture was then evaporated to dryness, and taken up in ethyl acetate/water. The organic layer was washed (water, brine), dried (MgSO4) and evaporated in vacuo. Chromatography on silica eluting with 10% ethyl acetate/hexane gave the title compound (2.8 g, 94%). 1H NMR (250 MHz, CDCl3) δ 8.46 (1H, s), 8.20 (1H, m), 6.93 (1H, m), 4.75 (1H, m), 1.42 (6H, d, J=7.5 Hz).
