Reaction Steps
2-[2-Bromo-5-(2-trimethylsilanyl-ethoxymethoxy)-phenyl]-ethanol (1.9 g, 6.0 mmol) was added to a solution of potassium hydroxide (1.35 g, 24 mmol) in DMSO (16 mL). Iodomethane (1.12 mL, 18 mmol) was added, and the solution stirred for 16 h. The reaction was diluted with water (50 mL) and extracted with ether (2×40 mL). Organics were washed with brine (40 mL), dried (Na2SO4) and concentrated in vacuo. Purification by silica gel chromatography (10% ether/hexanes) gave 1.28 g of {2-[4-bromo-3-(2-methoxy-ethyl)-phenoxymethoxy]-ethyl}-trimethyl-silane as a clear oil. 1H NMR (300 MHz, CDCl3) δ 7.40 (d, 1H, J=8.7 Hz), 6.96 (d, 1H, J=3.0 Hz), 6.80 (dd, 1H, J=8.7, 3.0 Hz), 5.18 (s, 2H), 3.74 (t, 2H, J=8.4 Hz), 3.60 (t, 2H, J=7.2 Hz), 3.37 (s, 3H), 2.98 (t, 2H, J=7.2 Hz), 0.95 (t, 2H, J=8.4 Hz), −0.01 (s, 9H).
