Reaction Steps

1-(3-Bromobut-2-en-2-yl)-4-fluorobenzene (250 mg, 1.2 mmol) was dissolved in DMF (5 mL). 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 nitrogen gas was purged into the reaction mixture for 2 min. The contents were stirred at 85° C. overnight. Water (5 mL) was added and the solid mass was filtered under vacuum to obtain crude compound which was purified on silica gel (100-200 mesh) using 0-3% MeOH:DCM as eluent. The compound was further purified through reverse phase chromatography. Yield: 6 mg. 1H NMR (CD3OD, HCl salt) δ (ppm): 7.42 (m, 2H), 7.30 (s, 1H), 7.20 (m, 3H), 7.10 (d, 1H), 4.70 (d, 1H), 4.40 (d, 1H), 3.90 (m, 1H), 3.62 (m, 1H), 3.25 (m, 1H), 3.16 (s, 3H), 3.10 (m, 1H), 2.42 (s, 3H), 1.94 (d, 3H), 1.64 (d, 3H).
