Reaction Steps

4-(2-Bromo-1-phenylvinyl)pyridine (310 mg, 1.1 mmol) was dissolved in DMF (5 mL) and potassium phosphate (424 mg, 2 mmol) was added followed by copper (I) iodide (19 mg, 0.1 mmol) and L-proline (23 mg, 0.2 mmol). 2,3,4,5-Tetrahydro-2,8-dimethyl-1H-pyrido[4,3-b]indole (200 mg, 1 mmol) was added and the mixture purged with nitrogen for 2 min. The reaction mixture was stirred at 85° C. overnight. Water was added and the solid mass was filtered under vacuum. The crude product was purified on silica gel (100-200 mesh) using 0-10% MeOH:DCM as eluent. The compound was further purified through reverse phase HPLC. Yield: 15 mg. 1H NMR (CDCl3, free base) δ (ppm): 8.60 (d, 2H), 7.30-7.15 (m, 7H), 7.0 (m, 3H), 6.90 (d, 1H), 3.70 (s, 2H), 2.70 (m, 2H), 2.50 (s, 3H), 2.42 (s, 3H), 2.36 (m, 2H).
