Reaction Steps

To a mixture of 2-(5-chloro-1H-indol-1-yl)-5-(trifluoromethyl)benzonitrile (1.66 g) and ethylene glycol (18 mL) was added a 1 M aqueous sodium hydroxide solution (26 mL) at room temperature, followed by stirring at 180° C. for 16 hours. The reaction mixture was cooled to room temperature and neutralized by adding 1 M hydrochloric acid (26 mL), followed by extraction with ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous sodium sulfate. After filtration, the filtrate was concentrated under reduced pressure to obtain 2-(5-chloro-1H-indol-1-yl)-5-(trifluoromethyl)benzoic acid (1.67 g).
