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.

Workup

  1. filtrationThe solid is filtered
  2. washwashed with H2O
  3. dry with materialdried over sodium sulfate
