Reaction Steps

A mixture of 5-bromo-1-(4-methylbenzyl)-1H-indole (1.0 g, 3.33 mmol), benzeneboronic acid (0.621 g, 5.0 mmol), potassium carbonate (0.691 g, 5.0 mmol), and [1′1′-bis(diphenylphosphino)-ferrocene]dichloropalladium(II) complex with methylenechloride (1:1) (0.816 g, 1.0 mmol) in dioxane-water (10:1, 16.5 mL) was stirred at 70° C. for 2 day. The reaction mixture was diluted with water and extracted with ethyl acetate. The organic extract was washed with water and brine, and then concentrated to an oil. The residue was purified by flash column chromatography using hexane/ethyl acetate (96:4) as an eluant to give the title compound as a semi-solid (0.48 g, 49%). Mass spectrum (+ESI, [M+H]+) m/z 298. 1HNMR (300 MHz, DMSO-d6): δ 7.80 (s, 1H), 7.63 (d, 2H, J=8.4 Hz), 7.48 (d, 2H, J=11.1 Hz), 7.38-7.45 (m, 3H), 7.11 (m, 4H), 6.52 (d, 2H, J=2.8 Hz), 5.38 (s, 2H), and 2.22 ppm (s, 3H).
