실험 절차

LiOH.H2O (0.0076 g, 0.182 mmol, 10 equiv) was added to 5-((3,6-dibromo-9H-carbazol-9-yl)methyl)-3-(pyridin-2-yl)oxazolidin-2-one (0.0091 g, 0.0182 mmol) in a mixture of 208 μL THF and 23 μL H2O (v/v=9:1). The mixture was stirred at room temperature for 7 days. The reaction mixture was purified by silica gel chromatography using CH2Cl2/EtOAc as elute to afford 0.0071 g white solid as product, yield 41.0%.
