Reaktionsschritte

Carbon tetrabromide (0.47 g, 1.25 mmol) and triphenylphosphine (0.47 g, 1.25 mmol) were added to a solution of 2,5-dimethoxylbenzylalcohol (0.2 g, 1.19 mmol) in THF (10 ml) at room temperature. The mixture was stirred for two hours to form a precipitate which the preciptate was filtered off. The filtrate was evaporated and the crude product was chromatographed (ethyl acetate and hexane 7:3). The desired compound was isolated as a white solid (0.25 g, 93%).
