To a solution of compound benzyl 2-(4-hydroxy-4-methylpiperidin-1-yl)acetate (400 mg, 1.61 mmol) in methanol (10 mL) was added Pd/C (10%, 100 mg) and the mixture was stirred under hydrogen atmosphere at ambient temperature for 1 h. The mixture was filtered through a pad of Celite and the filtrate was concentrated to afford 2-(4-hydroxy-4-methylpiperidin-1-yl)acetic acid (250 mg, quantitative) as a colorless solid, which was used directly without further purification.
