Procedimiento

To a solution of tert-butyl 6-oxo-2-azaspiro[3.3]heptane-2-carboxylate (507 mg, 2.4 mmol) in MeOH (5.0 mL) was added NaBH4 (182 mg, 4.8 mmol) at 0° C. under N2. It was stirred at 0° C. for 30 min. The solution was concentrated by evaporator in vacuo to give crude solid. A saturated solution of NaHCO3 (30 mL) was added. The aqueous mixture was extracted with DCM (4×30 mL). The combined organic solution was dried over anhydrous Na2SO4 and then concentrated by evaporation in vacuo to afford tert-butyl 6-hydroxy-2-azaspiro[3.3]heptane-2-carboxylate (511 mg, 100%) as a white solid.
