Versuchsvorschrift
4-(2,4-Difluoro-phenyl)-4-hydroxy-piperidine-1-carboxylic acid tert-butyl ester (0.2 g) was dissolved in a solution of hydrogen chloride in dioxane (4 N, 1 mL). The mixture was stirred for 1 hour and the solvent removed by evaporation under vacuum. The solid was triturated from ether to afford the title compound as a pale yellow solid (0.08 g). LCMS m/z 214.25 [M+H]+. R.T.=1.06 min (Analytical Method 4).
