実験手順

To a de-aerated solution of 5-(2-bromophenyl)-2,8-dimethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (100 mg, 0.281 mmol), 6-hydroxypyridine-3-boronic acid pinacol ester (124 mg, 0.562 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 reaction mixture was concentrated under reduced pressure to dryness. The residue 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 afford crude material, which was purified by reverse phase HPLC to yield 5-(2-(2,8-dimethyl-3,4-dihydro-1H-pyrido[4,3-b]indol-5(2H)-yl)phenyl)pyridin-2-ol. 1H NMR (TFA salt, CD3OD) d (ppm): 7.59-7.68 (m, 3H), 7.4 (s, 1H), 7.3 (s, 1H), 6.98-7.18 (m, 3H), 6.82 (d, 1H), 6.23 (d, 1H), 4.7 (d, 1H), 4.37 (d, 1H), 3.7 (m, 1H), 3.4 (m, 1H), 3.0 (m, 4H), 2.8 (m, 1H), 2.4 (s, 3H).
