Versuchsvorschrift

With stirring, a solution of 2-propynyl chloride (40.31 g) in dry methanol (50 ml) was added dropwise to a solution of piperidine (92.14 g) in dry methanol (100 ml). The mixture was stirred at 25° C. for 3 hours and then filtered. The filtrate was concentrated under reduced pressure and the residue was distilled (boiling point: 163–165° C./atmospheric pressure).
