Versuchsvorschrift

15.15 g (70.7 mmol) of the benzyl alcohol IIIa and 21.86 g (63.7 mmol) of triphenyl-phosphonium hydrobromide in 240 ml of acetonitrile are heated at reflux for 5 hours. The solvent is evaporated under reduced pressure, and diethyl ether is then added. The solid is filtered and dried under reduced pressure.
