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), 2-(dimethylamino)pyrimidine-5-boronic acid pinacol ester (140 mg, 0.561 mmol) and K2CO3 (120 mg, 0.845 mmol) in DME (4 mL)-water (2 mL) was added Pd(PPh3)4 (16 mg, 0.013 mmol). The reaction mixture was stirred at 90° C. for 45 min. The solvent was removed under reduced pressure, residue diluted with water (20 mL) and extracted with EtOAc (50 mL). The organic layer was dried over anhydrous sodium sulfate, concentrated under reduced pressure to obtain crude, 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,N-dimethylpyrimidin-2-amine. 1H NMR (TFA salt, CD3OD) δ (ppm): 8.8 (s, 2H), 7.6-7.77 (m, 3H), 7.4 (d, 1H), 7.3 (s, 1H), 7.1 (d, 1H), 6.97 (d, 1H), 4.77 (d, 1H), 4.4 (d, 1H), 3.8 (m, 1H), 3.5 (m, 1H), 3.3 (s, 6H), 3.1 (m, 4H), 3.0 (m, 1H), 2.4 (s, 3H).
