Toluene → 6-(4-Trifluoromethoxyphenyl)-1-ethyl-1H-indole

Participants

Reaction Steps

Following the procedure described in Step 2 of Example 2, 6-bromo-1-ethyl-1H-indole (0.410 g , 1.83 mmol) was reacted with 4-trifluoromethoxybenzene boronic acid (0.422 g, 2.05 mmol), using tetrakis(triphenylphosphine)palladium (0.0651 g, 0.0563 mmol), and sodium carbonate (0.792 g, 7.47 mmol) in water (3.7 mL), ethanol (1.4 mL), and toluene (8 mL). Purification by flash chromatography using hexane as an eluant yielded the title compound as a yellow oil (0.312 g, 56%). 1HNMR (300 MHz, DMSO-d6): δ 7.85 (d, 2H, J=6.3 Hz), 7.8 (s, 1H), 7.65 (d, 1H, J=7.8 Hz), 7.4-7.5 (m, 3H), 7.35 (d, 1H, J=6.2 Hz), 6.45 (d, 1H, J=2.3 Hz), 4.3 (q, 2H, J=7.0 Hz), and 1.4 ppm (t, 3H, J=7.0 Hz).
