Versuchsvorschrift

2-Bromophenol (3.46 g) was mixed with tetrahydrofuran (60 ml) and triphenylphosphine (6.3 g) was added along with 4-fluorophenethyl alcohol (4.2 g). The mixture was cooled in an ice bath before dropwise addition of diisopropyl azodicarboxylate (4.85 g). The mixture was allowed to warm to room temperature over 18 h. The mixture was evaporated and diethyl ether (100 ml) was added. Stirring was continued for 3 h, the mixture was filtered and the filtrate was evaporated. The product was purified by column chromatography eluting with ethyl acetate/hexane mixtures to give a yellow oil (4.47 g).
