実験手順

To a degassed stirred solution of 5-(2-bromocyclopent-1-enyl)-2,8-dimethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (100 mg, 0.29 mmol), 3-pyridinylboronic acid (71 mg, 0.577 mmol) and potassium carbonate (120 mg, 0.87 mmol) in 1,2-dimethoxyethane (4 mL)-water (2 mL) was added Pd(PPh3)4 (16 mg, 0.0147 mmol). The reaction mixture was stirred at 90° C. for 45 min. The reaction mixture concentrated, residue diluted with water (20 mL) and extracted with EtOAc (50 mL). The organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified by reverse phase HPLC to yield 2,8-dimethyl-5-(2-(pyridin-3-yl)cyclopent-1-enyl)-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole. 1H NMR (CD3OD, TFA salt) δ (ppm): 8.68 (d, 1H), 8.1 (d, 1H), 7.9 (m, 1H), 7.8 (m, 1H), 7.3 (s, 1H), 6.9-7.1 (m, 2H), 4.7 (m, 1H), 4.4 (m, 1H), 3.8 (m, 1H), 3.58 (m, 1H), 2.8-3.3 (m, 9H), 2.22-2.4 (m, 5H).
