Procedure

Spiro[indane-1,4'-piperidine]hydrochloride (0.4 g, 1.8 mmol) was dissolved in water (20 ml), and the solution made alkaline using solid sodium carbonate. The mixture was extracted with ethyl acetate (5×20 ml), and the organic layers combined and dried (MgSO4). The solvent was removed in vacuo to give spiro[indane-1,4'-piperidine] as a clear oil, which was used without further purification.
