Reaktionsschritte
A mixture of 5-((3,6-dibromo-9H-carbazol-9-yl)methyl)oxazolidin-2-one (0.0195 g, 0.0460 mmol), 2-iodopyridine (0.0209 g, 0.102 mmol), CuI (0.0009 g, 0.00460 mmol), and K2CO3 (0.0058 g, 0.0418 mmol) in 0.5 mL of DMSO was sealed tightly in a vial and heated at 130° C. for 12 hours. The reaction mixture was cooled and diluted with 20 mL EtOAc and washed with water 5×10 mL. The organic layer was dried over anhydrous Na2SO4 and evaporated to afford the crude product, which was subjected to silica gel chromatography using CH2Cl2/EtOAc as elute to afford 0.0183 g white solid as product, yield 79.4%.
