Versuchsvorschrift
Dissolve {2-[4-(2-chloro-pyridin-3-yl)-piperazin-1-yl]-ethyl}-methyl-carbamic acid tert-butyl ester (4.900 g, 13.807 mmol) in dichloromethane (100 mL). Slowly add 4N HCl in dioxane (20.711 mL, 82.845 mmol). Stir at room temperature for 18 hr. Concentrate and wash the resulting solid with diethyl ether to afford the title preparation (7.500 g, 99% yield). MS ES: m/z=255 [M+H]+.
