Reaction Conditions

Reaction Steps

To 2-(5-trifluoromethyl-pyridin-2-yl)-ethylamine (200 mg, 1.05 mmol) was added 6-bromo-1-methyl-1H-indole (685 mg, 2.10 mmol), cuprous iodide (10 mg, 0.05 mmol) and cesium carbonate (685 mg, 2.1 mmol) under an argon atmosphere. Then DMF (400 μl) and 2-acetylcyclohexanone (28 μl, 0.21 mmol) were added and the reaction mixture was stirred for 4 h at 120° C. After cooling to ambient temperature the reaction mixture was separated between tert-butylmethylether (2×20 ml) and water (15 ml). The combined organic layers were washed with brine (15 ml) and dried over sodium sulfate. Concentration and purification by chromatography (SiO2, heptane:ethyl acetate=100:0 to 67:33) afforded the title compound (114 mg, 34%) as a light brown oil. MS m/e: 320.1 [M+H]+.
