Reaction Steps

A mixture of potassium carbonate (27.6 g, 0.2 mol), 2-methoxy-4-nitrophenol (16.9 g, 0.1 mol), 1,2-dibromoethane (94 g, 0.50 mol) and acetonitrile was refluxed for 2 days, concentrated, extracted in ethyl acetate with water three times, dried, filtered, concentrated to a white powder, triturated with ether, filtered, then concentrated to give a pale yellow powder (15.8 g, 58%). 1H NMR (300 MHz, DMSO-d6) δ 7.90 (d, 1H), 7.80 (s, 1H), 7.20 (d, 1H), 4.55 (t, 2H), 3.80 (s, 3H), 3.75 (t, 2H) ppm.
