Versuchsvorschrift

A solution of phenyl 4-[(4-pyridyl)thio]-1-piperidine-carboxylate (5.0 g) in conc. hydrochloric acid (50 ml) was refluxed for 7 hours and concentrated to dryness in vacuo. The crystalline residue was washed with isopropanol and recrystallized from methanol to give 4-[(4-pyridyl)thio]piperidine dihydrochloride (2.85 g).
