Reaktionsschritte

To a solution of 2-methoxy-4-methylphenol (500 mg, 3.62 mmol) in acetonitrile (20 mL) was added 1,3-dibromopropane (3.65 g, 201.89 mmol) followed by cesium carbonate (2.35 g, 7.24 mmol). The resulting solution was heated at 85° C. for 48 h, then cooled to rt. The solution was filtered through a Celite® pad. The Celite® was washed with acetone, and the combined filtrates were concentrated under reduced pressure to give the title compound as a white solid (395 mg, 42%). GC/MS (EI) m/z 258 (M)+, RT 7.94 min.
