実験手順

Following the procedure described in Step 2 of Example 5, 6-bromo-1-[4-(tert-butyl)benzyl]-1H-indole (0.488 g, 1.43 mmol) was coupled to 4-trifluoromethoxybenzene boronic acid (0.329 g, 1.60 mmol), using tetrakis(triphenylphosphine) palladium (0.0574 g, 0.0496 mmol) and sodium carbonate (0.617 g, 5.82 mmol) in water (2.8 mL), ethanol (1.4 mL) and toluene (10 mL). Purification by flash chromatography using hexane as an eluant yielded 1-[4-(tert-butyl)benzyl]-6-[4-(trifluoromethoxy)phenyl]-1H-indole as a white solid (0.372 g, 61%), mp 100-102° C. 1HNMR (200 MHz, DMSO-d6): δ7.8 (d, 3H, J=8.5 Hz), 7.65 (d, 1H, J=8.5 Hz), 7.55 (d, 1H, J=3.5 Hz), 7.3-7.5 (m, 5H), 7.15 (d, 2H, J=7.5 Hz), 6.5 (d, 1H, J=3.5 Hz), 5.45 (s, 2H), and 1.2 ppm (s, 9H).
