Reaktionsschritte

A solution of sesamol (6.9 g; 50 mmol) in DMF (100 mL) under N2 was cooled to 0° C. and sodium hydride (60% w/w dispersion; 2.3 g; 60 mmol) carefully added. The slurry was allowed to warm to room temperature over 1 hour after which time 1-bromooctane (13 mL; 75 mmol) was added. The mixture was stirred for 5 days, poured onto H2O and extracted with diethylether (2×). The combined organic fractions were dried (MgSO4), filtered and evaporated in vacuo to yield 12.8 g (quantitative yield) of a white solid. Mp. 120° C.
