Under a nitrogen atmosphere, a solution of sesamol (2.00 g, 14.48 mmol) in DMF (15 mL) was slowly added over 5 min to a cold (0-5° C.), stirring slurry of sodium hydride (0.65 g of an 80% dispersion in mineral oil, 21.67 mmol) in DMF (10 mL). The mixture was allowed to warm to ambient temperature and further stirred for 1 h. To this slurry was added drop-wise over 5 min, 1-chloro-3-iodopropane (3.55 g, 1 7.37 mmol), and the resulting brown mixture was stirred at ambient temperature for 4 h. Cold water (25 mL) was carefully added, followed by saturated NaCl solution (25 mL). The resulting mixture was extracted with ether (4×50 mL). The combined ether extracts were dried (MgSO4), filtered, concentrated by rotary evaporation to a residue that was dried briefly under high vacuum producing a brown oil.
