Reaction Steps

To 4-(11-(2-ethylhexyl)-5-(4-fluoro-benzoyl)-11H-benzo[a]carbazol-8-yl]-4-oxo-butyric acid ethyl ester (1.01 g, 1.75 mmol) in dimethylsulfoxide (DMSO) (10 mL) are added K2CO3 (738 mg, 5.33 mmol) and carbazole (297 mg, 1.77 mmol). The reaction mixture is heated to 150° C. and stirred overnight. After cooling to room temperature, the reaction mixture is poured into water, and the crude product is extracted with CH2Cl2. The organic layer is washed with water and brine, dried over MgSO4. After concentration, the crude product is purified by column chromatography on silica gel eluting with CH2Cl2 to obtain a brown resin (760 mg; 60%). The structure is confirmed by 1H-NMR spectrum (CDCl3). δ [ppm]: 0.84 (t), 0.92 (t), 1.20-1.52 (m), 2.28-2.36 (m), 2.82 (t), 3.48 (t), 4.16 (q), 4.74-4.21 (m), 7.33 (t), 7.46 (t), 7.60 (d), 7.63 (d), 7.68 (t), 7.72 (t), 7.77 (d), 8.15 (t), 8.19 (d), 8.22 (d), 8.50 (s), 8.58 (d), 8.67 (d), 8.81 (s).
