실험 절차
To an ice-cold solution of 1-tert-butyl 4-ethyl 4-allylpiperidine-1,4-dicarboxylate (2 g, 6.70 mmol) in 1,4-dioxane (10 mL) was added HCl-dioxane (4.0 M, 15 mL) solution and the mixture stirred at rt for 30 min. After completion of reaction (by TLC), the solvent was evaporated to obtain a brownish solid material (1.30 g) that was carried forward to the next step without further purification. MS: 198.28 [M+H]+.
