Versuchsvorschrift

tert-Butyl 4-hydroxy-4-[2-(trifluoromethyl)phenyl]piperidine-1-carboxylate (0.40 g, 1.0 mmol) was dissolved in a 2.0 M solution of HCl in ether (5 mL). After being stirred at room temperature overnight, the solution was diluted with ether. The white solid was filtered and washed with ether to give 170 mg of pure product. MS calculated for C12H14F3NO: (M+H) 246; found 246.1.
