실험 절차

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), 2-(dimethylamino)pyrimidine-5-boronic acid pinacol ester (129 mg, 0.578 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 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 and concentrated. The residue 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)cyclopent-1-enyl)-N,N-dimethylpyrimidin-2-amine. 1H NMR (CD3OD, TFA salt) δ (ppm): 7.8 (d, 2H), 7.3 (s, 1H), 6.98-7.1 (m, 2H), 4.7 (m, 1H), 4.38 (m, 1H), 3.8 (m, 1H), 3.5 (m, 1H), 2.78-3.1 (m, 15H), 2.4 (s, 3H), 2.2 (m, 2H).
