Versuchsvorschrift

To a de-aerated solution of 5-(3-bromophenyl)-2,8-dimethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (100 mg, 0.281 mmol), 4-isoquinolineboronic acid (96.8 mg, 0.56 mmol) and K2CO3 (116 mg, 0.84 mmol) in DME-water (2:1) was added Pd(PPh3)4 (16 mg, 0.014 mmol). The reaction mixture was heated at 90° C. for 45 min. The reaction mixture was concentrated under reduced pressure. The residue obtained was dissolved in EtOAc (50 mL) and washed with water (20 mL). The organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure to obtain crude, which was purified by reverse phase HPLC to yield 5-(3-(isoquinolin-4-yl)phenyl)-2,8-dimethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole. 1H NMR (TFA salt, CD3OD) d (ppm): 9.5 (s, 1H), 8.57 (s, 1H), 8.4 (d, 1H), 8.09 (d, 1H), 8.0 (dd, 1H), 7.8-7.95 (m, 2H), 7.7 (d, 1H), 7.6 (m, 2H), 7.37 (s, 1H), 7.21 (d, 1H), 7.07 (d, 1H), 4.7 (m, 1H), 4.4 (m, 1H), 3.81 (m, 1H), 3.61 (m, 1H), 3.1-3.3 (m, 5H), 2.4 (s, 3H).
