Reaction Steps

To a solution of 6-(4-trifluoromethoxyphenyl)-1H-indole (0.853, 3.08 mmoles) in dry THF (10 mL) was added sodium hydride (60% dispersion on mineral oil, 0.47 g, 12.3 mmol), portionwise. The reaction mixture was stirred under nitrogen for 30 minutes and, then cooled in ice bath. A solution of iodomethane (0.38 mL, 6.1 mmole) in dry THF (10 mL) was added and the reaction mixture was stirred for 1 hour at room temperature. The mixture was then poured into excess water, acidified with 2N hydrochloric acid and extracted with ethyl acetate. The organic phase was washed with brine, dried over anhydrous magnesium sulfate and evaporated to dryness. The residue was purified by flash chromatography (Biotage apparatus) using 0.5% t-butyl methyl ether in hexane as an eluant. The title compound was obtained as a cream-colored solid that was vacuum dried at 66° C. (0.623 g, 70%). 1HNMR (300 MHz, DMSO-d6): δ7.85 (d, 2H, J=8.3 Hz), 7.75 (s, 1H), 7.65 (d, 1H, J=8.3 Hz), 7.45 (d, 2H, J=8.3 Hz), 7.3-7.4 (m, 2H), 6.45 (s, 1H), and 3.85 ppm (s, 3H).
