A 2 N sodium hydroxide aqueous solution (1 ml) and methanol (1 ml) were added to the obtained 2-(2-methyl-6-trifluoromethyl-1H-indol-3-yl)acetic acid methyl ester, and the mixture was heated to reflux for one hour. Water was added to the reaction mixture, which was then rendered acidic with concentrated aqueous hydrochloric acid, extracted with ethyl acetate, dried over sodium sulfate and concentrated under reduced pressure, to obtain 79 mg of the title compound as a colorless powder (6% yield).
