Versuchsvorschrift

To a solution of 3-fluoro-9-(2-(2-methoxyethoxy)ethyl)-9H-carbazole (1.06 g, 3.71 mmol) in chloroform (20 ml) was added NBS (0.66 g, 3.71 mmol) batch-wise in an ice-water bath. After complete addition, the reaction mixture was allowed to warm to room temperature slowly and stirred overnight. The reaction mixture was washed with water and brine. The organic layer was dried over anhydrous sodium sulfate and evaporated under reduced pressure to give compound 6 in 84% yield. 1H NMR (400 MHz, CDCl3) δ 8.09-8.06 (m, 1H), 7.63-7.60 (m, 1H), 7.52-7.50 (m, 1H), 7.36-7.26 (m, 2H), 7.21-7.16 (m, 1H), 4.40 (d, J=5.6 Hz, 2H), 3.82-3.80 (m, 2H), 3.49-3.46 (m, 2H), 3.40-3.38 (m, 2H), 3.29 (s, 3H). 13C NMR (100 MHz, CDCl3) δ 158.7, 156.3, 140.1, 137.4, 128.9, 124.2, 124.2, 123.2, 122.3, 122.2, 114.4, 114.1, 111.8, 110.8, 110.0, 109.9, 106.2, 106.0. HRMS (MALDI-TOF) m/z Calcd for C17H17BrFNO2 366.0499. Found 366.0502[M]+.
