실험 절차

To a solution of tert-Butyl-2-(4-methoxy-4-oxobutyl)piperidine-1-carboxylate (3) (25.67 g, 89.9 mmol) in Methanol was added dropwise acetyl chloride. The reaction mixture was stirred for 5 h at room temperature. The completion of the reaction was controlled via Thin-layer chromatography. After completion the reaction mixture was evaporated in vacuum to give Methyl 4-(piperidin-2-yl)butanoate hydrochloride (4) (20.14 g, 100%)
