Versuchsvorschrift
In a 500 ml flask was added 0.88 g of freshly washed (with hexane) KH (2.2 eq, 22 mmoles). To this was added 100 ml THF, 50 ml DMF, and 10 mmoles of 2-phenylcyclohexane carbonitrile and the contents were heated at reflux under N2 for 3 hours. After 3 hours, a solution of 1.5 eq of freshly distilled 3-N,N-dimethylaminopropyl chloride (9.83 g) dissolved in 25 ml THF was added dropwise and the reaction then heated at reflux overnight.
