실험 절차

Title compound 354 (3.1 g, 11.8 mmol), sodium hydride (565 mg, 14.14 mmol) and methyliodide (0.88 mL, 14.14 mmol) were stirred together in DMF (60 mL) at room temperature for 6 hours. DMF was removed and the residue was partitioned in EtOAc and water. The organic layer was dried, filtered and evaporated. The crude product was purified by flash chromatography (3:1 to 1:2 hexane:ethyl acetate) to afford title compound 357 (2.3 g, 60%) as a white solid.
