Procedure
To a solution of tert-butyl 4-hydroxy-4-(trifluoromethyl)piperidine-1-carboxylate (0.07 g, 0.26 mmol) in dichloromethane (1 mL) was added trifluoroacetic acid (1 mL). The resulting mixture was stirred at room temperature for 30 minutes. Concentration and drying afforded 4-(trifluoromethyl)piperidin-4-ol (0.044 g, 100%). MS (EI) for C6H10F3NO: 269 (MH+).
