実験手順

To a degassed solution of 5-(2-bromophenyl)-2,8-dimethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (300 mg, 0.84 mmol), N-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzamide (328 mg, 1.27 mmol) and K3PO4 (445 mg, 0.706 mmol), in DMF (6 mL)-water (0.6 mL) was added dichlorobis (triphenylphosphine) palladium (II) (30 mg, 0.042 mmol). The reaction mixture was heated at 90° C. for 95 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 HPLC to yield 2′-(2,8-dimethyl-3,4-dihydro-1H-pyrido[4,3-b]indol-5(2H)-yl)-N-methylbiphenyl-4-carboxamide. 1H NMR (TFA salt, CD3OD) δ (ppm): 7.57-7.78 (m, 5H), 7.4 (dd, 1H), 7.25 (s, 1H), 6.92-7.2 (m, 4H), 4.6 (m, 1H), 4.2 (m, 1H), 3.6 (m, 1H), 3.4 (m, 1H), 3.1 (m, 1H), 2.83 (m, 6H), 2.5 (m, 1H), 2.4 (s, 3H).
