Procedure

The title compound of Example 41 was prepared as follows. LiOH.H2O (0.0157 g, 0.373 mmol) was added to 5-((3,6-dibromo-9H-carbazol-9-yl)methyl)-3-(pyridin-4-yl)oxazolidin-2-one (0.0187 g, 0.0373 mmol) in a mixture of 428 μL THF and 48 μL H2O (v/v=9:1). The mixture was stirred at room temperature for 3 days. The reaction mixture was diluted with 30 mL EtOAc and washed with brine 3×30 mL. The organic layer was dried over anhydrous Na2SO4 and evaporated to afford the crude product, which did not require purification (0.0013 g white solid, 7.3%).
