Versuchsvorschrift

Add benzyl bromide (7.97 g, 46.6 mmol) to a solution of 2-iodo-benzene-1,3-diol (5.00 g, 21.2 mmol) and cesium carbonate (15.2 g, 46.6 mmol) in dimethylformamide (200 mL) and stir. After 18 hours, concentrate under reduced pressure. Add water (500 mL) and stir. After 1 hour, filter the resulting precipitate washing with water and hexanes to yield the title compound as an off-white solid (6.30 g, 71%): 1H NMR (CDCl3) δ 5.18 (s, 4H), 6.55 (d, 2H), 7.19 (t, 1H), 7.29-7.53 (m, 10H).
