Versuchsvorschrift
A mixture of 4-cyanophenol (35.7 g, 0.3 mol), K2CO3 (41.4 g, 0.3 mol) and 1,2-dibromoethane (561 g, 3.0 mol) in MeCN (450 mL) was stirred under reflux overnight. The mixture was filtered and evaporated to give 30.2 g (45%) of the sub-title compound, which was used without further purification.
