Reaktionsschritte

A 250 mL round-bottom flask equipped with stir bar was charged with 7-octen-1-ol (1.20 mL, 7.80 mmol). Anhydrous DMF (60 mL) was added, and the solution was allowed to cool to 0° C. (ice-bath). Sodium hydride (2.40 g, 40.0 mmol) was added in portions, and the mixture was allowed to stir until gas evolution ceased. p-Methoxybenzyl chloride (2.1 mL, 16 mmol) was added by a syringe and the mixture was allowed to stir for 24 h. The reaction was quenched by addition of a saturated aqueous solution of sodium bicarbonate (100 mL), and washed with ethyl acetate (5×100 mL). The combined organic layers were washed with water (3×100 mL) to remove dmf, further washed in brine (1×50 mL), dried over MgSO4, filtered, and concentrated in vacuo. The resulting yellow oil was purified by silica gel chromatography (96:4 hexanes:EtOAc), delivering 1-methoxy-4-((oct-7-en1-yloxy)methyl)benzene (946 mg, 3.81 mmol, 49.0% yield) as a colorless oil.
