Versuchsvorschrift

To compound 2 (3.92 g, 17.24 mmol) in DMF (133 mL) was added NBS (3.37 g, 19.0 mmol). The solution was heated to 60° C. After 1 h, the solution volume was reduced to approximately one half the volume, and the solution was poured into H2O (700 mL). The precipitate was filtered, washed with water, and dried to yield 5.08 g of 3. 1H NMR (400 MHz, d6-DMSO) δ: 11.84 (s, 1H), 8.05 (s, 1H), 7.82 (d, J=7 Hz, 2H), 7.61 (s, 1H), 7.48 (t, J=7 Hz 2H), 7.4 (t, J=7 Hz, 1H).
