Reaction Steps

A solution of 2,8-dimethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (0.4 g, 4 mmol), 2-Bromonaphthalene (0.828 g, 4 mmol), K3PO4 (0.848 g, 4 mmol), CuI (38 mg, 0.2 mmol) and L-Proline (46 mg, 0.39 mmol) in dry DMF (6 mL) was stirred at 150° C. for 16 h. 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 phase HPLC to yield 2,8-dimethyl-5-naphthalen-2-yl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole as an off white solid (50 mg). 1H NMR (HCl salt, CD3OD) d (ppm): 8.15 (d, 1H), 8.05-7.95 (m, 2H), 7.9 (s, 1H), 7.6 (m, 2H), 7.5 (d, 2H), 7.35 (s, 1H), 7.19 (d, 1H), 7.05 (d, 1H), 4.8 (d, 1H), 4.45 (d, 1H), 3.8-3.79 (m, 1H), 3.6-3.59 (m, 1H), 3.3-3.25 (m, 1H), 3.19 (s, 3H), 3.05-3.0 (m, 1H), 2.45 (s, 3H).
