실험 절차

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, 0.28 mmol), N-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)picolinamide (148 mg, 0.56 mmol) and K2CO3 (115 mg, 0.84 mmol) in DME-water (2:1) was added Pd(PPh3)4 (16 mg, 0.014 mmol). The reaction mixture was stirred at 90° C. for 2 h, additional Pd (PPh3)4 (16 mg, 0.014 mmol) was added into the reaction mixture and stirring continued at 90° C. for 12 h. The reaction mixture was concentrated under reduced pressure. The residue was dissolved in EtOAc (30 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)-N-methylpicolinamide as an off-white solid. 1H NMR (TFA salt, CD3OD) d (ppm): 8.21 (d, 1H), 7.82 (d, 1H), 7.76 (m, 3H), 7.6 (d, 2H), 7.23 (s, 1H), 6.9 (d, 2H), 4.7 (m, 1H), 4.3 (m, 1H), 3.63 (m, 1H), 3.42 (m, 1H), 2.8-3.1 (m, 7H), 2.6 (m, 1H), 2.4 (s, 3H).
