Reaction Steps

Following the procedure described in Step 2 of Example 5, 6-bromo-1-methyl-1H-indole (1.12 g, 5.33 mmol) was coupled to 4-(tert-butyl)phenylboronic acid (1.07 g, 6.00 mmol), using tetrakis(triphenylphosphine) palladium (0.655 g, 0.567 mmol), and potassium carbonate (2.94 g, 21.3 mmol) in water (10.6 mL), ethanol (2.2 mL), and toluene (23 mL). Purification by flash chromatography (Biotage apparatus) using 0-1% ethyl acetate in hexane as an eluant then drying at 60° C. yielded 6-[4-(tert-butyl)phenyl]-1-methyl-1H-indole as a yellow solid (0.790 g, 56%), mp: 92-94° C. 1HNMR (200 MHz, DMSO-d6): δ 7.55-7.7 (m, 5H), 7.45 (d, 2H, J=7.5 Hz), 7.3 (d, 2H, J=8.5 Hz), 6.6 (d, 1H, J=3.5 Hz), 3.9 (s, 3H), and 1.3 ppm (s, 9H).
