実験手順
Combine piperidine (5.0 g, 58.7 mmol), fused sodium acetate (4.82 g, 58.7 mmol) and 1,3-dibromopropane (11.85 g, 58.7 mmol) and reflux for several hours. Pour the mixture into water and add sodium carbonate to create a basic pH. Remove the unreacted 1,3-dibromopropane by distillation. Extract the left-over residue with ether and evaporate to obtain the final, desired compound.
