Reaction Steps

4-Bromo-2-nitrophenol (5.0 g, 23 mmol) and potassium carbonate (9.52 g, 69 mmol) were suspended in 2-butanone (100 ml). Ethyl iodide (2.2 ml, 28 mmol) was added dropwise at room temperature and stirred for 30 minutes. The suspension was heated at reflux for 18 hours, cooled and filtered, and the residue washed with acetone. The filtrate was concentrated in vacuo to a crude solid that was used without further purification (D14). 1H-NMR (CDCl3) δ 7.42 (1H, d, J 2.5 Hz), 7.60 (1H, dd, J 9.0, 2.5 Hz), 6.96 (1H, d, J 9.0 Hz), 4.17 (2H, q, J 7.0 Hz), 1.47 (3H, t, J 7.0 Hz).
