Versuchsvorschrift
A solution of tert-butyl 4-(1H-imidazol-2-yl)piperidine-1-carboxylate (5.5 g) in methanol was saturated with HCl and the mixture was left standing overnight. Evaporation give the product in quantitative yield. 1H NMR (400 MHz, D2O): 7.29 (s, 2H), 3.51 (br. d, J=13 Hz, 2H), 3.47-3.40 (m, 1H), 3.12 (br. t, J=13 Hz, 2H), 2.29 (br. d, J=14 Hz, 2H), 2.04-1.92 (m, 21).
