Participants

Reaction Steps

The title compound was prepared from 1-bromo-2-ethylbutane (14.14 mL, 101 mmol) and 5-bromoindole (20 g, 101 mmol) in substantially the same manner, as described in Step 1 of Example 25. The product (17.78 g, 62%) was obtained as a colorless oil. Mass spectrum (ESI, [M+H]+) m/z 280. 1 HNMR (400 MHz, DMSO-d6): δ 7.71 (d, 1H, J=1.83 Hz), 7.43-7.39 (m, 2H), 7.21 (dd, 2H, J=8.72 and 1.99 Hz), 6.41 (d, 1H, J=2.90 Hz), 4.04 (d, 2H, J=7.48 Hz), 1.76 (hep, 1H), 1.21 (p, 4H), and 0.82 ppm (t, 6H).
