Reaction Steps
Add sodium hydride (0.430 g of 60% in oil, 10.75 mmol) to DMF (100 mL) at −5° C. Add (3-bromo-2,5-bis-methoxymethoxy-phenyl)-methanol (3.00 g, 9.77 mmol) in DMF (20 mL) in portions and stir the resulting solution at −5° C. for 1 hour. Add methyl iodide (0.67 mL, 10.75 mmol) and stir the reaction for 1 hour. Pour the reaction into ice-H2O (200 mL) and extract with EtOAc (2×50 mL). Combine the extracts and wash with H2O (2×100 mL) and brine (50 mL) then dry (MgSO4), filter and concentrate. Purify the residue by silica gel chromatography eluting with Hex:EtOAc (80:20) to provide the subtitled product (2.76 g, 88%) as an oil. 1H NMR (CDCl3) δ 3.41 (s, 3H), 3.47 (s, 3H), 3.62 (s, 3H), 4.54 (s, 2H), 5.03 (s, 2H), 5.13 (s, 2H), 7.06 (d, J=2.9 Hz, 1H), 7.20 (d, J=2.9 Hz, 1H).
