Reaction Steps
To a de-aerated solution of 5-(3-bromophenyl)-2,8-dimethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (100 mg, 0.281 mmol), indazole-4-boronic acid hydrochloride (111 mg, 0.559 mmol) and K2CO3 (116 mg, 0.845 mmol) in DME (4 mL)-water (2 mL) was added Pd(PPh3)4 (16 mg, 0.013 mmol). The reaction mixture was stirred at 90° C. for 45 min. The reaction mixture was concentrated under reduced pressure. The residue was dissolved in EtOAc (50 mL) and washed with water (20 mL). The organic layer was dried over anhydrous sodium sulfate, concentrated under reduced pressure to obtain crude, which was purified by reverse phase HPLC to yield 5-(3-(1H-indazol-4-yl)phenyl)-2,8-dimethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole. 1H NMR (TFA salt, CD3OD) d (ppm): 8.18 (s, 1H), 7.82 (d, 1H), 7.78 (t, 1H), 7.7 (s, 1H), 7.6 (d, 1H), 7.5 (m, 2H), 7.34 (m, 2H), 7.21 (d, 1H), 7.1 (d, 1H), 4.7 (d, 1H), 4.4 (d, 1H), 3.8 (m, 1H), 3.6 (m, 1H), 3.04-3.18 (m, 5H), 2.4 (s, 3H).
