Sodium triacetoxyborohydride (3.18 g, 15.00 mmol) and acetic acid (0.859 mL, 15.00 mmol) were added to a solution of piperidin-4-ol (1.011 g, 10 mmol) and oxetan-3-one (0.721 g, 10.00 mmol) in DCE (35 mL) and the reaction mixture was stirred at room temperature overnight. Celite was added to the sticky reaction mixture and the reaction mixture was filtered, the filtrate was concentrated in vacuo to give a brown oil. The solid was purified by flash chromatography on silica gel using an automated ISCO system (120 g column, eluting with 0-8% 2 N ammonia in methanol/dichloromethane). 1-(oxetan-3-yl)piperidin-4-ol (0.80 g) was obtained as a white solid.
