Versuchsvorschrift

To a solution of tert-butyl 4-(3,4-difluorobenzyl)-4-hydroxypiperidine-1-carboxylate (4.7 g) in ethanol (30 mL) was added 2.0 M HCl/ethanol solution (36 mL), and the mixture was stirred overnight at room temperature. The solvent was evaporated under reduced pressure, and the obtained solid was recrystallized from ethyl acetate/diisopropyl ether to give the title compound (3.5 g).
