실험 절차
A solution of 1'-(tert-butyloxycarbonyl)spiro[indene-1,4'-piperidine] (3.0 g, 0.011 mol) in ethyl acetate (150 ml) was stirred at 0° C., and treated with hydrogen chloride for 30 minutes. The mixture was then evaporated to dryness, ethyl acetate (100 ml) was added, then removed in vacuo three times. The residue was stirred with anhydrous ether (200 ml), and the solid filtered off, to give spiro[indene-1,4'-piperidine] hydrochloride (2.3 g, 99%) as a pale yellow solid. The product was not purified further.
