Reaction Steps
5-Allyl-8-chloro-2,3,4,5-tetrahydro-2-methyl-1H-pyrido[4,3-b]indole (300 mg, 1.15 mmol, 1 equiv.) and 5-bromo-2-methylpyridine (198 mg, 1.15 mmol, 1 equiv.) were heated to 100° C. with palladium acetate (7.8 mg, 0.034 mmol), triphenyl phosphine (18 mg, 0.069 mmol) and triethyl amine (0.35 mL, 2 equiv.) in THF (6 mL) for 14 h. The reaction mixture was cooled to RT and diluted with THF (10 mL), filtered over a Celite bed and concentrated. The concentrate was dissolved in EtOAc (20 mL) and washed with water (5 mL) followed by brine. The organic layer was dried over anhydrous sodium sulfate, and evaporated under reduced pressure to obtain crude product that was purified by HPLC. 1H NMR (CD3OD) δ (ppm): 8.57 (s, 1H), 8.39-8.37 (d, 1H), 7.74-7.72 (d, 1H), 7.51 (s, 1H), 7.41 (d, 1H), 7.17 (d, 1H), 6.78-6.72 (m, 1H), 6.28-6.24 (d, 1H), 5.02 (m, 2H), 4.7 (bs, 1H), 4.36 (bs, 1H), 3.87 (bs, 1H), 3.6 (bs, 1H), 3.29-3.24 (m, 2H), 3.12-3.10 (s, 3H), 2.7 (s, 3H).
