Reaction Steps

Potassium carbonate (17.8 g, 0.13 mol) followed by benzyl bromide (5.12 mL, 42.9 mmol) were added to a solution of 2-ethyl-5-propoxy-phenol (7.74 g, 42.9 mmol) in DMF (60 mL). The mixture was stirred at 45° C. for 15 hours and then partitioned between H2O and EtOAc. The organic layer was washed with 1 N HCl, brine, dried over Na2SO4 and concentrated to a brown oil. Purification by flash column chromatography (0% to 20% EtOAc in hexanes) gave the product as a clear oil (6.1 g, 55%). 1H NMR (400 MHz, CDCl3): δ 1.02 (t, J=7.6 Hz, 3 H), 1.19 (t, J=7.6 Hz, 3 H), 1.78 (q, J=7.6 Hz, 2 H), 2.63 (q, J=7.6 Hz, 2 H), 3.88 (t, J=6.6 Hz, 2 H), 5.05 (s, 2 H), 6.44 (dd, J8.1, 2.3 Hz, 1 H), 6.51 (dd, J=2.3 Hz, 1 H), 7.05 (d, J=8.3 Hz, 1 H), 7.31 (m, 1 H), 7.38 (m, 2 H), 7.44 (m, 2 H).
