실험 절차

9H-Carbazol-4-ol (0.367 g, 2.0 mmol) was placed in a flask with DMF (10 mL) and NaH (60% dispersion in oil, 77 mg, 2.0 mmol) and stirred for 30 min at room temperature. (S)-glycidyl 3-nitrobenzene sulfonate (0.52 g, 2.0 mmol) was added to the reaction mixture, which was then stirred at room temperature for 14 hours. The reaction was quenched with NaHCO3 (saturated) and then extracted with ethyl acetate (3×). The organic layer was dried with magnesium sulfate, filtered and the solvent evaporated under reduced pressure to yield crude product which was purified by silica gel chromatography (60% Ethyl acetate/heptane) to yield the title compound as a residue.
