Versuchsvorschrift
2,6-Dimethylisoquinolin-1-one (120.0 mg, 0.60 mmol) in acetic acid (4 mL) was treated with Br2 (96 mg, 0.6 mmol) in acetic acid (0.6 mL) at 0° C. in a manner similar to Example 72, step 2. Isolation, also in a similar manner, gave the title compound (145.0 mg, 82.9%) as a white yellow solid. 1H NMR (CDCl3, 400 MHz) δ 8.33 (d, J=8.0 Hz, 1H), 7.60 (s, 1H), 7.37 (d, J=8.0 Hz, 1H), 7.35 (s, 1H), 3.60 (s, 3H), 2.54 (s, 3H). LCMS: 252.1 (M+H)+
