Versuchsvorschrift

A 250-mL 3-necked round-bottomed flask was charged with tert-butyl 3-cyanopiperidine-1-carboxylate (5.8 g, 27.07 mmol, 1.00 equiv, 98%) in 1,4-dioxane (60 mL). The mixture was cooled down to at 0° C. and treated with HCl (g). The mixture was stirred for 2 hours at 0° C. resulting in a precipitate that was collected by filtration to afford piperidine-3-carbonitrile hydrochloride as white solid (1.9 g, 48%).
