Reaction Steps
To an ice-cold solution of O1-tert-butyl O4-ethyl 4-cyanopiperidine-1,4-dicarboxylate (0.4 g, 1.41 mmol) in 1,4-dioxane (10 mL) was added HCl-dioxane (4 M, 5 mL) solution. The resulting mixture was stirred at rt for 30 minutes. After completion of reaction (by TLC), solvent was evaporated to obtain the product as a solid (0.28 g). MS: 183.27 [M+H]+.
