실험 절차

To a solution of tert-butyl 4-(4-cyanobenzyl)-4-hydroxypiperidine-1-carboxylate (19 g) in 1,4-dioxane (50 mL) was added 4.0 M HCl/1,4-dioxane solution (76 mL) at 0° C., and the mixture was stirred at room temperature for 10 hr. The resulting solid was collected by filtration, washed with ethyl acetate (100 mL) and diethyl ether (200 mL), and dried under reduced pressure to give the title compound (9.3 g).
