실험 절차

A solution of 4-phenylbutan-2-ol (97.7 mg, 0.651 mmol), Nor-AZADO (0.90 mg, 6.51 μmol, 1 mol %) and acetic acid (37 μl, 0.651 mmol) in dichloromethane (0.65 ml) was added with DIAD (128 μl, 0.651 mmol, 1 equivalent), and the mixture was stirred for 8 hours under reflux by heating. The reaction mixture was added with saturated aqueous sodium carbonate (2 ml), and the mixture was extracted with dichloromethane. The organic layer was dried over sodium sulfate, and then concentrated under reduced pressure. The residue was purified by silica gel column chromatography to obtain the objective compound (95.1 mg; yield, 99%). The spectrum data were found to be the same as those obtained in Example 5, (b).
