Versuchsvorschrift

To a degassed solution of 5-(3-bromophenyl)-2,8-dimethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (101 mg, 0.286 mmol), N-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)picolinamide (150 mg, 0.57 mmol) and K2CO3 (236 mg, 1.71 mmol) in DME-water (2:1) was added Pd(PPh3)4 (33 mg, 0.028 mmol). The reaction mixture was stirred at 90° C. for 45 min. The reaction mixture concentrated under reduced pressure. The residue was dissolved in EtOAc (50 mL) and washed with water (20 mL). The organic layer dried over anhydrous sodium sulfate and concentrated under reduced pressure to afford crude material, which was purified by reverse phase HPLC to yield 5-(3-(2,8-dimethyl-3,4-dihydro-1H-pyrido[4,3-b]indol-5(2H)-yl)phenyl)-N-methylpicolinamide. 1H NMR (TFA salt, CD3OD) d (ppm): 8.97 (s, 1H), 8.23 (d, 1H), 8.12 (d, 1H), 7.85 (d, 1H), 7.78 (m, 2H), 7.5 (d, 1H), 7.37 (s, 1H), 7.21 (d, 1H), 7.04 (d, 1H), 4.76 (m, 1H), 4.4 (m, 1H), 3.8 (m, 1H), 3.6 (m, 1H), 3.08-3.21 (m, 5H), 3.0 (s, 3H), 2.4 (s, 3H).
