Versuchsvorschrift

A mixture of 1-bromo-3-butene (1.35 g, 10 mmol) and piperidine (1.70 g, 20 mmol) neat was refluxed under nitrogen atmosphere for 3 h. Cooled to RT, filtered and dissolved into ethyl ether (40 mL). Then solution was washed with water (2×30 mL) and dried over anhydrous Na2SO4, filtered and evaporated to dryness to yield 1.3 g (74.15%) oily 1-piperidyl-3-butene.
