Reaction Steps
To a solution of 2,5-dipropylphenol (3.50 g, 19.6 mmol) and iodomethane (3.70 mL, 58.8 mmol) in DMF (65 mL) at 0° C. was added sodium hydride (1.60 g, 39.2 mmol, 60% dispersion in oil) in two portions. The resulting mixture was stirred at 0° C. for 10 min and then at room temperature for 14 h. After being quenched with water, the mixture was extracted in hexanes (3×100 mL) with 50% saturated brine (50 mL). Flash chromatography with silica gel (100% hexanes) afforded the title compound as a colorless liquid (3.70 g, 97% yield): 1H NMR (300 MHz, CDCl3) δ 0.95 (two overlapping triplets, 6H), 1.60 (m, 4H), 2.55 (m, 4H), 3.81 (s, 3H), 6.66 (s, 1H), 6.70 (d, 1H, J=7.5 Hz), 7.02 (d, 1H, J=7.5 Hz).
