Procedure
1-Benzyl-4-hydroxy-piperidine-4-carbonitrile (5 g, 23.12 mmol) is dissolved in a mixture of H2SO4 (18 mL) and H2O (2 mL) at 0° C. The mixture is warmed to room temperature for 14 hours, transferred into cold 2 N NaOH and adjusted to pH>8. The solid is filtered and washed with H2O, and dried over sodium sulfate to give the crude product.
