Reaction Steps
The mixture of methyl 2-[6-(4-trifluoromethoxyphenyl)-1-methyl-1H-indol-3-yl]-2-oxoacetate (0.120 g, 0.318 mmol), and sodium hydroxide (1N, 1 mL, 1.0 mmol) in methanol (10 mL), was stirred at room temperature for 2.5 hours. The mixture was poured into excess water and acidified with 1N hydrochloric acid. The mixture was extracted with ethyl acetate. The organic phase was washed with water, brine and dried over anhydrous magnesium sulfate. The organic phase was evaporated to dryness and dried under vacuum at 55° C. for 12 hours to yield the title compound as a yellow solid (0.0686 g, 59.1%), mp: 233-235° C. (dec). Mass spectrum (+APCI, [M+H]+) m/z 364; 1HNMR (400 MHz, DMSO-d6): δ13.8-14.0 (br s, 1H), 8.55 (s, 1H), 8.25 (d, 1H, J=8.3 Hz), 7.95 (d, 1H, J=1.1 Hz), 7.85-7.95 (m, 2H), 7.65 (dd, 1H, J=8.2 and 1.6 Hz), 7.45 (dd, 2H, J=8.8 Hz and 0.88 Hz), add 4.0 ppm (s, 3H). Elemental Analysis for C19H14F3NO4: Calculated: C, 59.51; H, 3.33; N, 3.86. Found: C, 59.39; H, 3.38; N, 3.71.
