Reaction Steps

4-(1-Bromoprop-1-en-2-yl)-N,N-dimethylbenzamide (264 mg, 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 compound was purified on silica gel (100-200 mesh) using 0-7% MeOH:DCM as eluent. Yield: 60 mg. 1H NMR (CD3OD, oxalate salt) δ (ppm): 7.30 (m, 2H), 7.20 (s, 2H), 7.10 (d, 1H), 6.95 (d, 1H), 6.86 (s, 1H), 6.80 (s, 1H), 4.58 (m, 1H), 4.30 (m, 1H), 3.60 (m, 1H), 3.10 (m, 1H), 3.0 (s, 3H), 2.92 (s, 3H), 2.80 (m, 2H), 2.50 (s, 3H), 2.39 (s, 3H), 2.36 (s, 3H).
