実験手順

1-[4-(tert-Butyl)benzyl]-5-[4-(trifluoromethoxy)phenyl]-1H-indole was prepared by coupling 1-[4-(tert-Butyl)benzyl]-5-bromo-1H-indole (5.34 g, 15.6 mmol), and 4-trifluoromethoxyphenyl boronic acid (3.86 g, 18.7 mmol), using [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) complex with dichloromethane (1:1) (0.453 g, 0.555 mmol), and potassium carbonate (3.22 g, 23.3 mmol) in dioxane (120 mL) and water (11.8 mL) following the procedure described in Step 1 of Example 11. Purification by flash chromatography (Biotage apparatus) using hexane as the mobile phase yielded a dark yellow gum that solidified upon standing to a light yellow solid (2.53 g, 38%). 1HNMR (300 MHz, DMSO-d6): δ 7.95 (s, 1H), 7.75 (d, 2H, J=7.7 Hz), 7.55-7.6 (m, 2H), 7.45 (d, 3H, J=7.7 Hz), 7.35 (d, 2H, J=7.7 Hz), 7.15 (d, 2H, J=7.7 Hz), 6.45 (d, 1H, J=3.9 Hz), 5.4 (s, 2H), and 1.2 ppm (s, 9H).
