실험 절차

To [11-(2-ethylhexyl)-5-(4-fluorobenzoyl)-11H-benzo[a]carbazol-8-yl]-(2,4,6-trimethylphenyl)-methanone (1.29 g, 2.16 mmol) in pyridine (3 ml) are added 2,2,3,3-tetrafluoro-1-propanol (0.43 g, 3.24 mmol) and sodium hydroxide (0.13 g, 3.32 mmol). The mixture is stirred at 70° C. for 23 hours, and then it is stirred at 120° C. for 24 hours. After the reaction mixture is cooled at room temperature, it is poured into water, and then the crude product is extracted with AcOEt, and washed with water and brine. After drying over MgSO4 and concentration, the crude product is purified by column chromatography on silica gel eluting with CH2Cl2 to obtain a white solid (0.80 g, 51%). The product is composed of an isomeric mixture, and the structure is confirmed by 1H-NMR spectrum (CDCl3) δ [ppm]: 0.79-0.99 (m), 1.24-1.52 (m), 2.05 (s), 2.13 (s), 2.35 (s), 2.37 (s), 4.31 (t), 4.73-4.77 (m), 5.90-6.16 (m), 6.83 (d), 6.87 (d), 6.92 (s), 6.94 (s), 7.50-7.73 (m), 7.88 (d), 8.00 (s), 8.11 (br), 8.19 (s), 8.41 (br), 8.55 (d), 8.62 (d); 19F-NMR spectrum (CDCl3). δ [ppm] −125.04, −124.90.
