Reaction Conditions

Reaction Steps

Lithium aluminium hydride (1.0M solution in tetrahydrofuran, 1.41 mL, 1.41 mmol, 1.0 eq) is added at 0° C. to a stirred solution of [1-(2-cyclopropyl-2-oxo-ethyl)-piperidin-4-yl]-carbamic acid tert-butyl ester (420 mg, 1.41 mmol, 1.0 eq) in tetrahydrofuran (25 mL). After 2 hours stirring at 0° C., the reaction mixture is cautiously quenched with ice-water (5 mL). Tetrahydrofuran in evaporated and the crude is extracted with dichloromethane (3×30 mL) and water (30 mL). The combined organic layers are dried over sodium sulfate, filtered and concentrated to afford [1-(2-cyclopropyl-2-hydroxy-ethyl)-piperidin-4-yl]-carbamic acid tert-butyl ester as a white solid (373 mg, 84% yield).
