Versuchsvorschrift

A solution of HCl in dioxane (4M, 30 mL) was added to a solution of tert-butyl 3-[1-(3-fluorophenyl)methylidene]piperidine-1-carboxylate (Intermediate 227, 2.38 g) in ether (30 mL) and the mixture was stirred at room temperature for 5 hours. The mixture was concentrated in vacuo and the residue was treated with ether. The solid was collected by filtration, washed with ether and dried under vacuum to give 3-[1-(3-fluorophenyl)methylidene]piperidine hydrochloride (1.64 g).
