Procedure
Acetyl chloride (0.222 mL, 3.08 mmol) was added to a stirring solution of {1-(4-methylbenzyl)-5-[4-(trifluoromethoxy)phenyl]-1H-indol-2-yl}methanol (0.507 g, 1.23 mmol) and N,N-diisopropylethylamine (0.547 mL, 3.08 mmol) in methylene chloride (8 mL) at 0° C. under a nitrogen atmosphere over a period of 5 minutes. After the reaction mixture was stirred at room temperature overnight, the reaction was quenched carefully with water. The aqueous mixture was extracted with ethyl acetate. The organic extract was washed with water and brine, dried over anhydrous magnesium sulfate and evaporated to afford the title compound as a solid (0.557 g, 99.6%), mp: 125-126° C. Mass spectrum (ESI, [M+H]30 ) m/z 454. 1HNMR (400 MHz, DMSO-d6): δ 7.86 (s, 1H), 8.77 (d, 2H, J=8.96 Hz), 7.48-7.40 (m, 4H), 7.09 (d, 2H, J=7.94 Hz), 6.90 (d, 2H, J=7.94 Hz), 6.70 (s, 1H), 5.44 (s, 2H), 5.23 (s, 2H), 2.23 (s, 3H), and 1.85 ppm (s, 3H).
