To a solution of 2,2-dimethyl-6′-morpholinospiro[[1,3]dioxane-5,3′-indolin]-2′-one (0.11 g, 0.35 mmol) in toluene (14 mL) was added sodium bis(2-methoxyethoxy)aluminium hydride (60% in toluene, 0.53 mL, 1.74 mmol). After stirring at 80° C. for 40 min, the solution was poured into a mixture of ice and 2N NaOH. The product was extracted with DCM and the combined organic extracts were dried over MgSO4, filtered and evaporated in vacuo. Purification by column chromatography (eluting with a gradient of 5-60% EtOAc in hexanes) gave 2,2-dimethyl-6′-morpholinospiro[[1,3]dioxane-5,3′-indoline] as a white solid. Mass Spectrum (ESI) m/e=305.2 (M+1).
