Reaction Steps

(3-(1-Bromoprop-1-en-2-yl)phenyl)(methyl)sulfane (194 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 0-4% MeOH:DCM as eluent. Yield: 160 mg. 1H NMR (CD3OD, oxalate salt) δ (ppm): 7.50 (s, 1H), 7.38 (m, 2H), 7.30 (s, 2H), 7.10 (m, 2H), 6.99 (s, 1H), 4.50 (m, 2H), 3.70 (m, 2H), 3.10 (m, 4H), 2.56 (s, 3H), 2.42 (s, 3H), 1.95 (s, 3H)
