Reaction Steps
Add 1-bromomethyl-4-iodo-benzene (10.00 g, 33.7 mmol) to a solution of 1-(2,4-dihydroxy-3-propyl-phenyl)-ethanone (6.54 g, 33.7 mmol) and cesium carbonate (13.2 g, 40.4 mmol) in acetone (500 mL) and stir. After 48 hours, pour the reaction into water and extract with ethyl acetate. Combine the organic layers, dry with sodium sulfate, filter and concentrate under reduced pressure to give a residue. Purify the residue by flash chromatography eluting with a gradient of ethyl acetate:hexanes to yield the title product as a yellow solid (7.20 g, 52%): 1H NMR (CDCl3) δ 0.95 (t, 3H), 1.56 (sextet, 2H), 2.56 (s, 3H), 2.69 (t, 2H), 5.09 (s, 2H), 6.43 (d, 1H), 7.15 (d, 2H), 7.57 (d, 1H), 7.73 (d, 2H), 12.74 (s, 1H).
