실험 절차

Acetyl chloride was slowly added dropwise to a solution of tert-butyl 2-(4-methoxy-4-oxobutyl)piperidine-1-carboxylate (3) (25.67 g, 89.9 mmol) in methanol. The reaction mixture was stirred at room temperature for 5 h. The complete reaction was checked by means of TLC. When the reaction was complete, the reaction mixture was concentrated under reduced pressure to obtain methyl 4-(piperidine-2-yl)butanoate hydrochloride (4) (20.14 g, 100%).
