実験手順
To a de-aerated solution of 5-(2-bromo-phenyl)-2,8-dimethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (100 mg, 0.282 mmol), 3-pyridinylboronic acid (51 mg, 0.420 mmol) and K3PO4 (149 mg, 0.706 mmol) in DMF-water (4:1 mL) was added PdCl2(PPh3)2 (10 mg, 5 mol %). The reaction mixture was heated at 95° C. for 30 min under nitrogen atmosphere. The reaction mixture was diluted with water and extracted with EtOAc. 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 2,8-dimethyl-5-(2-pyridin-3-yl-phenyl)-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole as a semisolid (30 mg). 1H NMR (Oxalate salt, CD3OD) δ (ppm): 8.30 (s, 1H), 8.10 (s, 1H), 7.70 (m, 3H), 7.56 (d, 1H), 7.50 (d, 1H), 7.24 (m, 2H), 6.98 (d, 1H), 6.82 (d, 1H), 4.50 (m, 2H), 3.60 (m, 2H), 3.05 (s, 3H), 2.95 (m, 1H), 2.62 (m, 1H), 2.40 (s, 3H).
