실험 절차

To a mixture di-tert-butyl[{4-[(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)oxy]piperidin-1-yl}methylylidene]biscarbamate 64 (2.30 g, 4.71 mmol) in a solution of DCM (40 mL) and ethanol (6 mL) was added hydrazine hydrate (0.270 mL, 4.71 mmol) at room temperature. The mixture was stirred at room temperature overnight, filtered and concentrated to provide a residue which was subjected to chromatography to give 65 (0.72 g, 43%) as a white foam.
