Reaction Steps

3-(1-Bromoprop-1-en-2-yl)-N-methylbenzamide (202 mg, 0.8 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 (100-200 mesh) using 0-7% MeOH:DCM as eluent. Yield: 101 mg. 1H NMR (CD3OD, oxalate salt) δ (ppm): 8.1 (s, 1H), 7.8 (m, 2H), 7.6 (t, 1H), 7.3 (s, 1H), 7.15 (d, 1H), 7.1 (d, 1H), 7.05 (s, 1H), 4.6 (bs, 2H), 3.7 (bs, 2H), 3.1 (bs, 5H), 3.0 (s, 3H), 2.4 (s, 3H), 2.0 (s, 3H).
